mmc: core: general purpose MMC partition support.
It allows gerneral purpose partitions in MMC Device. And I try to simply
make mmc_blk_alloc_parts using mmc_part structure suggested by Andrei
Warkentin. After patching, we see general purpose partitions like this:
> cat /proc/partitions
179 0 847872 mmcblk0
179 192 4096 mmcblk0gp3
179 160 4096 mmcblk0gp2
179 128 4096 mmcblk0gp1
179 96 1052672 mmcblk0gp0
179 64 1024 mmcblk0boot1
179 32 1024 mmcblk0boot0
