spi: s3c64xx: clear loopback bit after loopback test
[ Upstream commit 9ec3c5517e22a12d2ff1b71e844f7913641460c6 ]
When SPI loopback transfer is performed, S3C64XX_SPI_MODE_SELF_LOOPBACK
bit still remained. It works as loopback even if the next transfer is
not spi loopback mode.
If not SPI_LOOP, needs to clear S3C64XX_SPI_MODE_SELF_LOOPBACK bit.
