spi: xilinx_spi: Add support ops to axi qspi driver
Add support_ops function to check controller supported operations by
spi-mem framework. Current default support ops function does not allow
dummy buswidth no more than 1, unless we are using buswidth is 4 for TX.
In order to support dummy buswidth > 1 by spi-nor framework we are adding
explicit support_ops to check controller supported operations.
Fix dummy bytes calculation incase of valid dummy bytes when dummy
buswidth is > 1. Current dummy bytes calculation does not provide
correct dummy values for dummy buswidth > 1.
