mtd: parsers: scpart: fix __udivdi3 undefined on mips

[ Upstream commit 105c14b84d93168431abba5d55e6c26fa4b65abb ]

This fixes the following compile error on mips architecture with clang
version 16.0.0 reported by the 0-DAY CI Kernel Test Service:
   ld.lld: error: undefined symbol: __udivdi3
   referenced by scpart.c
   mtd/parsers/scpart.o:(scpart_parse) in archive drivers/built-in.a

As a workaround this makes 'offs' a 32-bit type. This is enough, because
the mtd containing partition table practically does not exceed 1 MB. We
can revert this when the [Link] has been resolved.
