Use bus_space_read rather than kmemdup to read ROM.

jakllsch@ reports that on some 64-bit systems, kmemdup does 8-byte
reads, which yield garbage in the high word. bus_space_read_region_1
does 1-byte reads instead, which seem to work.

Derived from a patch from jakllsch@.

Fix two issues in NetBSD implementation of igp_read_bios_from_vram():

* Allocate the correct buffer for the VGA BIOS image.
* Abort if buffer allocation failed, not if buffer allocation succeeded.

Not directly tested, but I can't imagine this makes anything worse.

drm: enable almost all PCIe functionality

linux_pci.c revisions 1.24 and 1.25 implemented most of the remaining
missing PCIe backends, but only enabled them for some amdgpu portions.

this enables all code marked with "XXX amdgpu pcie", "XXX radeon pcie",
and "XXX pcie speed". for most of it, simply removing #ifndefs __NetBSD__
to enable compliation was required, once the new "bus->max_bus_speed"
member was added to struct pci_bus. add an "always fails" backend for
pci_enable_atomic_ops_to_root() which seems to only be necessary
for virtual GPU functionality (and could be implemented if needed.)

tested on radeon 5450, 7750, R7 240 [radeon], and RX 550 [amdgpu], and
nvidia 750 and 1030 [nouveau].


this still does not quite work on nvidia cards. there are two problems
that remain:

- the call to set the link speed is skipped because the speed is set
to the default value of "-1". nvkm_pcie_set_link() will actually
determine the right value for this and for some cards, calling this
function if the current speed is -1 helps set the link speed. it
may be that on linux other paths we don't have enabled properly
would set this (there's one via debugfs, and a jetson specific one,
though perhaps setting either AC or DC speed values as boot options
(after hooking up these for netbsd) would currently work.

- worse, cards newer than kepler - geforce 900, 1000, and newer, are
all lacking the backing support to set pcie link speed. the GT 1030

the pci and ppb devices.

Latter is a mistake that is all my fault. Oops.

don't apply the "don't set CLUT" to RV280. it isn't necessary for
my PCI 9250 card, and hoses the colours in X when running.

unfortunately, my RV250 does need this to avoid the console being
very very dark on black.

i'm curious what other earlier radeon card (anything matching any
of the card marked as: CHIP_R100, CHIP_RV100, CHIP_RS100,
CHIP_RV200, CHIP_RS200, CHIP_R200, CHIP_RV250, and CHIP_RS300.)


the RV280 now works again properly, but the RV250 is still having
a problem waiting for commands to complete and it appears as if
X is hung, when infact it is asking the kernel quite frequently
if the job it asked for is complete, each time sleeping for a
short time and thus only appearing to take almost no CPU.

Hack against the blank console problem:
Leave the CLUT alone on ancient cards. At least this leaves us with a
semi working console (red and blue are flipped). Leave an example of what
seems to be happening but disable it because colors are better than 444 bit
greyscale.

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?).
