spi: spi-fsl-dspi: Use whole page for DMA buffers

Browse source

dma_alloc_noncoherent() allocations are backed by a full page anyway, so
use it all.

VF610 devices used to use the full page before commit a957499bd4
("spi: spi-fsl-dspi: Fix bits-per-word acceleration in DMA mode"), but
others still used the FIFO size. After that commit, all devices used the
FIFO size. Now all devices use the full page.
