mmc: core: Fix size overflow for mmc partitions
[ Upstream commit f3d7c2292d104519195fdb11192daec13229c219 ]
With large eMMC cards, it is possible to create general purpose
partitions that are bigger than 4GB. The size member of the mmc_part
struct is only an unsigned int which overflows for gp partitions larger
than 4GB. Change this to a u64 to handle the overflow.
