[PATCH v7] mmc : general purpose partition support.

It allows gerneral purpose partitions in MMC Device. And I try to simpliy make mmc_blk_alloc_parts using mmc_part structure suggested by Andrei Warkentin. After patching, we can see general purpose partitions like this. > cat /proc/partitions 179 0 847872 mmcblk0 179 192 4096 m
