mtd: ubi: fix NVMEM over UBI volumes on 32-bit systems
A compiler warning related to sizeof(int) != 8 when calling do_div()
is triggered when building on 32-bit platforms.
Address this by using integer types having a well-defined size.
Fixes: 3ce485803da1 ("mtd: ubi: provide NVMEM layer over UBI volumes")
