Document zynqmp_qspi ctrl and op_lock member description. It also adds
return documentation for 'zynqmp_qspi_setuprxdma' and zynqmp_qspi_read_op.

Fixes below kernel-doc warnings-

spi-zynqmp-gqspi.c:178: warning: Function parameter or member 'ctlr' not
described in 'zynqmp_qspi'
spi-zynqmp-gqspi.c:178: warning: Function parameter or member 'op_lock'
not described in 'zynqmp_qspi'

spi-zynqmp-gqspi.c:737: warning: No description found for return value of
'zynqmp_qspi_setuprxdma'
spi-zynqmp-gqspi.c:822: warning: No description found for return value of
'zynqmp_qspi_read_op'
