The host controllers on TI's AM654 SOCs are not compatible with the phy and consumer model of the sdhci-of-arasan driver. It turns out that for optimal operation at higher speeds, a special tuning procedure needs to be implemented which involves configuration of platform specific phy registers. Therefore, branch out to a new sdhci_am654 driver and add the phy register space with all phy configurations to it. Populate AM654 specific callbacks to sdhci_ops and add SDHCI_QUIRKS wherever applicable. Only add support for upto High Speed for SD card and upto DDR52 speed mode for eMMC. Higher speeds will be added in subsequent patches.
