spi: pxa2xx: Remove rx_/tx_map_len members from struct driver_data
spi-pxa2xx-dma.c DMA engine implementation stopped using PIO for unaligned trailing bytes in the commit 111e0a9dc71e ("spi/pxa2xx: Prevent DMA from transferring too many bytes"). This means there is no need to update tx/rx transfer buffer pointers after DMA completion. These buffer pointers will be set to new buffers when handling the next transfer. Because this buffer pointer update was only remaining use for rx_map_len and tx_map_len members in struct driver_data after removing the legacy PXA DMA implementation they can be removed now.
