thorpej | Clean up gttwsi's register access stuff:
- Garbage-collect the obsolete GTTWSI_ALLWINNER option; it hasn't been
needed since FDT'ization of the Allwinner support code.
- Redefine thw "TWSI_*" register definitions to clearly call out:
-> The Marvell flavor of the offsets
-> The Allwinner flavor of the offsets
...and make the regular definitions indices into a register map.
- Pass the appropriate register map from the front-end to the core.
- Remove the customer register read/write callbacks -- they are no longer
needed now that each front-end passes an appropriate register map to
the core.

Remove assertions that no longer make sense now that the bus acquire / release
logic is handled by the upper layer.

Allow drivers to provide their own read/write register functions. While
here, sprinkle KASSERTs to verify that the i2c lock is held where it
should be.

On Allwinner A31 you need to set the CONTROL_IFLG bit to clear it. Add
a "iflg-rwc" property to enable this behaviour.

Make gttswi MI and usuable from non-Marvell SoCs.
(should rename to mvi2c but ...)

Don't assume that U-Boot has enabled the TWI clock. Also, for A31, set
the "iflg-rwc" device property for gttwsi.

The SoC RTC works on this board but does not seem to be hooked up to the
battery. Thankfully, there is a PCF8563 attached to TWI2 at address 51h,
so use that instead.

snj | Pull up following revision(s) (requested by bouyer in ticket #1061):
sys/dev/i2c/gttwsi_core.c: revision 1.4-1.8 via patch
sys/dev/i2c/gttwsivar.h: revision 1.4 via patch
Use IPL_VM for bus lock so we can do i2c xfers from interrupt context
Don't sleep with IPL_VM lock held.
When initiating a transfer, if a device isn't present, we won't
get an ACK after sending the address. Check for this alternate
state and suppress the error message when it occurs.
Fixes PR kern/53356.
Bail early if gttwsi_send_start() fails in gttwsi_initiate_xfer() to
avoid unexpected state error message later (on Allwinner H5).
Expand code covered by sc->sc_mtx, to make sure an interrupt would not be
handled before the cv_timedwait_sig() call, or while polling.
Seems to fix "sunxitwi0: send STOP failed" messages frequently seen related
to axp20x0 sensors.
