spi: bcm-qspi: Fix BSPI QUAD and DUAL mode support when using flex mode

[ Upstream commit 79629d0f7ce5b38515c1716911a0181f01b91102 ]

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")
