mmc: block: Allow disabling 512B sector size emulation
This patch adds support for large sector size of 4KB by disabling emulation. This patch passes eMMC DATA_SECTOR_SIZE as the logical block size during mmc_blk_alloc_req. In order to use this patch for 4KB sector size, ensure that USE_NATIVE_SECTOR is enabled, partition table is 4KB sector size aligned and file system block and sector size are 4KB multiples.
