Add support for MMC/SD controller nodes present on TI's j7200 SoCs.
There are two nodes:
1. sdhci0 (8 bit bus width, 200 MHz, HS200, 200 MBps)
2. sdhci1 (4 bit bus width, 50 MHz, HS, 25 MBps)

Add support for the eMMC and SD card connected on the common
processor board
sdhci0 is connected to an eMMC while sdhci1 is connected to the
micro SD slot.
