Add FDT matching code to AT91 device drivers.

Better nomatch messages: include compat string. Also, flag devices as
disabled in the successful probe message, but leave what that means to
the actual driver (no semantic changes).

Fix Embest board name and id.

Honor the disabled status by only grabbing resources and returning
when running under FDT in the AT91 SPI driver.

Copy head (r256279) to stable/10 as part of the 10.0-RELEASE cycle.

at91$DEV->at91_$DEV to match other Atmel drivers. Also, export
at91_rst_cpu_reset.

Make it possible to link together a sam and an rm kernel. The results
aren't very pretty yet, but this takes DELAY and cpu_reset and makes
them pointers.

# I worry that these are set too late in the boot, especially cpu_reset.

Add support for the Atmel SAM9XE familiy of microcontrollers, which
consist of a ARM926EJ-S processor core with up to 512 Kbytes of on-chip
flash. Tested with SAM9XE512.

- Try to bring these files closer to style(9).
- Use DEVMETHOD_END.
- Use NULL instead of 0 for pointers.

Add support for the AT91SAM9260

if_ate.c:

* Support for sam9 "EMAC" controller.
* Support for rmii interface to phy.

at91.c & at91sam9.c:

* Eliminate separate at91sam9.c file.
* Add new devices to at91sam9_devs table.

at91_machdep.c & at at91sam9_machdep.c:

* Automatic chip type determination.
* Remove compile time chip dependencies.
* Eliminate separate at91sam9_machdep.c file.

at91_pmc.c:

* Corrected support for all of the sam926? and sam9g20 chips.
* Remove compile time chip dependencies.

My apologies to Greg for taking so long to take care of it.
