spi: spi-s3c64xx: Allow higher transfer lengths in polling IO mode

Some variants of the SPI controller have no DMA support, in such case
SPI transfers longer than the FIFO length are not currently properly handled
by the driver. Fix it by doing multiple transfers in the s3c64xx_spi_transfer_one()
function if the SPI transfer length exceeds the FIFO size.
