u5500: Move the SD/MMC card to different phy chan
Currently, the eMMC and external SD/MMC card use same
physical channels in the same event group.
This patch moves the SD/MMC card to use a different
eventgroup. There are several cross cases in which both
these are used simultaneously. There seems to be an
improvement in performace of SD card cross use-cases if
these are in different channels.
