spi: spi-cadence: Enable spi refclk in slave mode
When spi-cadence is configured as a slave, it requires the SPI refclk to
detect the synchronization start condition while communicating with the
master. However, the spi-cadence driver never enables the SPI refclk in
slave mode, causing the refclk to remain disabled if the
"clk_ignore_unused" kernel parameter is not passed through bootargs.
As a result, the slave cannot detect data sent by the master, leading to
communication failure. Update driver to enable the SPI refclk in both
master and slave configurations.
Fixes: b1b90514eaa3 ("spi: spi-cadence: Add support for Slave mode")
