mmc: zynq: Determine base clock frequency via clock framework

The zynq_sdhci controller driver use CONFIG_ZYNQ_SDHCI_MAX_FREQ as base
clock frequency but this clock is not fixed and depends on the hardware
configuration. Additionally the value of CONFIG_ZYNQ_SDHCI_MAX_FREQ
doesn't match the real base clock frequency of SDIO_FREQ. Use the clock
framework to determine the frequency at run time.
