cmd_mtdparts: use 64 bits for flash size, partition size & offset
This matches the 64 bit size in struct mtd_info and allows the mtdparts command to function correctly with a flash >= 4GiB. Format specifiers for size & offset are given the ll length, matching its use in drivers/mtd in absence of something like inttypes.h/PRIx64.
