mmc: adding mmc and sdio support for cloverview

BZ: 16722

Cloverview SOC use different PCI Device IDs for eMMC/SDIO controllers
hence existing eMMC/SDIO driver won't be initialized on Cloverview SOC.

This patch adds eMMC and SDIO probing support for Cloverview SOC. Also,
Cloverview does not support eMMC mutex as comparing to Penwell hence not
to expose the Dekker's mutex mechanism for Cloverview.
