spi: spi-cadence: enable SPI_CONTROLLER_MUST_TX
During an SPI read operation, even if the xspi->txbuf passed to the
cdns_spi_writerinterface is empty, it is still necessary to call
cdns_spi_write(xspi, CDNS_SPI_TXD, txw); otherwise, the read operation
will fail to obtain data correctly due to a lack of clocks.
Fixes: 4e00135b2dd1 ("spi: spi-cadence: supports transmission with bits_per_word of 16 and 32")
