eSDHC could select peripheral clock or platform clock as clock source by the PCS bit of eSDHC Control Register, and this bit couldn't be reset by software reset for all. In default, the platform clock is used. But we have to use peripheral clock since it has a higher frequency to support eMMC HS200 mode and SD UHS-I mode. This patch is to add peripheral clock support and use it instead of platform clock if it's declared in eSDHC dts node.
