rename of_search_compatible() to of_compatible_lookup().

Standardize on of_compatible_match() for driver matching, and adapt

Use DEVICE_COMPAT_EOL.

Since we're using designated initialisers for compat data, we should
use a completely empty initializer for the sentinel.

Use device_compatible_entry / of_search_compatible() to match the clock
type rather than calling of_compatible() on different sets of compatible
strings.

move DWCGMAC_MPSAFE into dwc_gmac_var.h and introduce an
additional define that is 0 or FDT_INTR_MPSAFE that the
frontends can use when passing to fdtbus_intr_establish().

with NET_MPSAFE enabled, this avoids hangs seen on rock64,
as well as finishing the MPSAFE port for this driver.

Refactor the "platform" defitions into fdt_platform.h

Rename ARM_PLATFORM to FDT_PLATFORM and make it available outside arm.

Merge thorpej-cfargs branch:

Simplify and make extensible the config_search() / config_found() /
config_attach() interfaces: rather than having different variants for
which arguments you want pass along, just have a single call that
takes a variadic list of tag-value arguments.

Adjust all call sites:
- Simplify wherever possible; don't pass along arguments that aren't
actually needed.
- Don't be explicit about what interface attribute is attaching if
the device only has one. (More simplification.)
- Add a config_probe() function to be used in indirect configuiration
situations, making is visibly easier to see when indirect config is
in play, and allowing for future change in semantics. (As of now,
this is just a wrapper around config_match(), but that is an
implementation detail.)

Remove unnecessary or redundant interface attributes where they're not
needed.

There are currently 5 "cfargs" defined:
- CFARG_SUBMATCH (submatch function for direct config)
- CFARG_SEARCH (search function for indirect config)
- CFARG_IATTR (interface attribte)
- CFARG_LOCATORS (locators array)
- CFARG_DEVHANDLE (devhandle_t - wraps OFW, ACPI, etc. handles)

...and a sentinel value CFARG_EOL.

Add some extra sanity checking to ensure that interface attributes
aren't ambiguous.

Use CFARG_DEVHANDLE in MI FDT, OFW, and ACPI code, and macppc and shark
ports to associate those device handles with device_t instance. This
will trickle trough to more places over time (need back-end for pre-OFW
Sun OBP; any others?).

Call acpi_device_register() / fdtbus_device_register() as approrpriate.

cpu_hatched_p does necessary memory barrier so remove membar_consumer

Get rid of a4x bus_space tag from fdtbus_attach_args. The only consumer

Add support for KASAN on ARMv[67]

Thanks to maxv for many pointers and reviews.

Various updates and improvements to cpu start up on arm/aarch64

- start sharing more code around the AP startup messaging.
- call arm_cpu_topology_set early so that ci_core_id is available for
drivers, e.g. bcm2835_intr.c
- both arm and aarch64 now have
- a static cpu_info_store array
- the same arm_cpu_{hatched,mbox}

branches: 1.11.2; 1.11.6;
make CPU 1 bootstrapping work even if the kernel is not loaded close to PA 0.

More precisely, we used "B cpu_mpstart", which worked for small addresses and
thus does not work in the EFI case.
It is now replaced by a "LDR PC, =cpu_mpstart", which works for arbitrary
addresses.

Change ap_mpstart to return non-zero value if any/all APs don't start.

Adapt secondary CPU bootstrapping to the new generic startup code.

Make early console work.

. fix important typo which prevented enabling the SCU
. invalidate all cache tags of the SCU

Retire fdt_putchar and ap_early_put_char in favour of uartputc.

Use virtual addresses where virtual addresses are expected.

Clean up around cpu_ttb and fix a bunch of builds

Provide generic start code that assumes the MMU is off and caches are
disabled as per the linux booting protocol for ARMv6 and ARMv7 boards.
u-boot image type should be changed to 'linux' for correct behaviour.

The new start code builds a minimal "bootstrap" L1PT with cached access
disabled and uses the same table for all processors. AP startup is
performed in less steps and more code is written in C.

The bootstrap tables and stack are placed into an (orphaned) section
"_init_memory" which is given to uvm when it is no longer used.

Various kernels have been converted to use this code and tested. Some
boards were provided by TNF. Thanks!

The GENERIC kernel now boots on boards using the TEGRA, SUNXI and EXYNOS
kernels. The GENERIC kernel will also work on RPI2 using u-boot.

Thanks to martin@ and aymeric@ for testing on parallella and nanosoc
respectively

Step towards modularizing the Flattened Device Tree code.

Define attributes for each of the specific device bindings: clock,
dai, dma, gpio, i2c, iommu, mbox, mmc_pwrseq, phy, power, power domain,
pwm, regulator, reset controller, spi, system controller, pin
controller. Include these support files only if either a provider
or consumer with one of these attributes is present in the kernel
config.

Add the necessary attributes to the device / attach declarations for
each provider and consumer.

There are some bindings that are consumed by generic code (iommu, pinctrl,
power, power domain). Provide weak stubs for these routines to handle
situations where there is no provider.

No actual code changed; NFCI.
