spi: bcm-qspi: fix SFDP BFPT read by usig mspi read
SFDP read shall use the mspi reads when using the bcm_qspi_exec_mem_op()
call. This fixes SFDP parameter page read failures seen with parts that
now use SFDP protocol to read the basic flash parameter table.
Fixes: 5f195ee7d830 ("spi: bcm-qspi: Implement the spi_mem interface")
