[U-Boot] [PATCH 0/3] mmc: sdhci: Add support for frequency constrained peripheral interfaces

The sdhci controller assumes that the base clock frequency is fully
supported by the peripheral and doesn't support hardware limitations.
Distinguish between base clock of the host controller and maximal
supported peripheral clock frequency of the peripheral interface.
This is needed for the zynq platform to support two sdhci ports with
different IO routings.

    frequency
  mmc: zynq: Determine base clock frequency via clock framework
  mmc: zynq: Add fdt max-frequency support
