spi: s3c64xx: Fix large transfers with DMA
The COUNT_VALUE in the PACKET_CNT register is 16-bit so the maximum
value is 65535. Asking the driver to transfer a larger size currently
leads to the DMA transfer timing out. Implement ->max_transfer_size()
and have the core split the transfer as needed.
Fixes: 230d42d422e7 ("spi: Add s3c64xx SPI Controller driver")
