AT91: at91sam9g20ek: merge 2mmc version in one board
The board-sam9g20ek-2slot-mmc.c was a revision of the at91sam9g20ek
since board revision C. It contains 2 sd/mmc slots.
This merge keep the support of the old machine ID
MACH_AT91SAM9G20EK_2MMC for backward compatibility.
Now we use the ATAG to pass the hardware functionality to kernel
with this board revision encoding
bit 0:
0 => 1 sd/mmc slot
1 => 2 sd/mmc slots connectors (board from revision C)
system_rev tested on Barebox commit d8f3ee103a9f4bd
