spi: cadence: revert "Add SPI transfer delays" 



The commit 855a40cd ("spi: cadence: Add SPI transfer delays") adds a
delay after each transfer into the driver's transfer_one(). However,
the delay is already done in SPI core. So this commit unnecessarily
doubles the delay amount. Revert this commit.
