[PATCH v2 5/8] mmc: zynq_sdhci: Move setting tapdelay code to driver

tap_delays.c just has calls to xilinx_pm_request() for setting tapdelays.
Simply move these calls to zynq_sdhci.c and make them static inline.
Similarly zynqmp_tap_delay.h also has call to xilinx_pm_request() for
dll reset. Do the same for this file as well.

Remove tap_delays.c and zynqmp_tap_delay.h files.
