-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 v3:
-Remove max_chunk
-Remove tinydrm_spi_max_transfer_size()
-Change master->max_dma_len in patch 0/2 and explain why it is changed
