-Call spi_split_transfers_maxsize in __spi_pump_messages
to split large chunks for spi dma transfers.
-Remove chunk splitting in the tinydrm spi helper (as now the core is
handling the chunk splitting).
Changes in v2:
-Change the order of the two patches in the patchset.
-Undo the spurious blank line deletions
-Remove bcm2835_spi_transfer_one_message and add spi_split_transfers_maxsize
in __spi_pump_messages. This solves the DMA time out error.
