* 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.
