da850/omap-l138: modifications for Logic PD Rev.3 AM18xx EVM
AHCLKR/UART1_RTS/GP0[11] pin needs to be configured for
MMC and NOR to work on DA850/OMAP-L138 Rev.3 EVM. When
GP0[11] is low, the SD0 interface will not work, but NOR
flash will. When GP0[11] is high, SD0 will work but NOR
flash will not.
