S5P: mmc: Resolved interrupt error during mmc_init
Blocksize was hardcoded to 512 bytes. But the blocksize varies depeding on various mmc subsystem commands (between 8 and 512). This hardcoding was resulting in interrupt error during data transfer. It is now calculated based upon the request sent by mmc subsystem. Signed-off-by: Chander Kashyap <chander.kashyap@linaro.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
