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.
Changes in v3: - Rename arguments of sdhci_setup_cfg function from max_clk/min_clk to f_max/f_min
Changes in v2: - Remove unused index from get uart clock function - Remove unused index from get sdio clock function - Introduce common get clock function
