Revert "spi: cadence_qspi_apb: Use 32 bit indirect write transaction when possible"

This reverts commit 61b89b16fb915cb6d4da8f23067fb6ef08c546f6.

Using bounce_buf.c to handle non-DMA alignment problems is bad as
bounce_buf.c does cache manipulations which is not required. Therefore
revert this patch in favour of local bounce buffer solution in the next
patch.
