spi: cadence_quadspi: Enable QUAD mode based on DT data
Instead of relying on CONFIG_SPI_FLASH_QUAD to be defined to enable QUAD
mode, make use of mode_rx field of dm_spi_slave_platdata to determine
whether to enable or disable QUAD mode. This is necessary to support
muliple SPI controllers where one of them may not support QUAD mode.
