spi: spi-zynqmp-gqspi: Add tap delay support for ZynqMP GQSPI Controller
GQSPI controller uses the internal clock for loopback mode. The loopback
mode is used with the high-speed Quad SPI timing mode, where the memory
interface clock needs to be greater than 40 MHz. Based on the tap delay
value programmed, the internal clock is delayed and used for capturing
the data.
Based upon the frequency of operation set the recommended tap delay
values in GQSPI driver.
