Add Support for eMMC in TI's AM65x-evm. The series starts by syncing the sdhci0 node from the kernel. Then it adds APIs and changes to the driver required for handling the driver's integrated phy. The current maximum supported speed is DDR52. Higher speeds and tuning support will be added in a subsequent series.
Support for booting from eMMC will also be added in subsequent patches.
Tested on Lokesh's branch[1] as sysfw loading for AM65x is not yet upstream.
