Split arasan_zynqmp_set_tapdelay() to handle input and output tapdelays separately. This is required to handle zero values for ITAP and OTAP values. If we dont split, we will have to remove the if() in the function, which makes ITAP values to be overwritten when OTAP values are called to set and vice-versa. Restrict tap_delay value calculated to max allowed 8 bits for ITAP and 6 bits for OTAP for ZynqMP.
