spi: zynq-qspi: Clarify the select chip function
The code used to assert and de-assert a chip select line is very complicated for no reason. Simplify the logic by either setting or resetting the concerned bit, which actually only changes an electrical state. Update the comment to reflect that there is no possibility to actually choose a CS as the default (CS0) will be driven in any case.
