Subject: [PATCH 5/5] mmc: sdhci: update Makefile/Kconfig for sdhci_pltfm change

The sdhci_pltfm.c becomes a file only having common support functions
than a driver with its registeration before.  The patch is to update
Makefile and Kconfig to let MMC_SDHCI_PLTFM be selected by specific
SDHCI device drivers.
