Vincent Whitchurch b22226d4e1 spi: s3c64xx: Fix large transfers with DMA 
[ Upstream commit 1224e29572f655facfcd850cf0f0a4784f36a903 ]

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")
