spi: bcm-qspi: Fix BSPI QUAD and DUAL mode support when using flex mode
Fix data transfer width settings based on DT field 'spi-rx-bus-width'
to configure BSPI in single, dual or quad mode by using data width
and not the command width.
Fixes: 5f195ee7d830c ("spi: bcm-qspi: Implement the spi_mem interface")
