Ashok Reddy Soma 728d21b8c7 mmc: zynq_sdhci: Add common function to set input/output tapdelays
Remove setting tapdelays for different speeds separately. Instead use
the ITAP and OTAP delay values which are read from the device tree.
If the DT does not contain tap delay values, the predefined values
will be used for the same.
