ARM: S5PV210: Add SDHCI devices for GONI board

This patch add support for SDHCI blocks on Samsung Goni board. The
following host controllers are defined:
1. Internal MoviNAND device (permanently wired to the controller)
2. Internal WiFI SDIO device (card is activated by power regualor)
3. External MMC/SD socket (card detection is provided by external
gpio interrupt)
