eMMC and SDXC interface controller share the common driver since IP block
of the vendor(SDHC-ARASAN) is same, where as PHY is different. The PHY 
is designed by Intel itself to support
specific eMMC card and SD/SDIO card specific. e.g: PAD, CLK, driver 
strength..etc.

IP block of the PHY  is different module for eMMC and SDXC to adapt the 
controllers, that is reason we have different drivers.
