From: Arnd Bergmann <arnd@xxxxxxxx>
On 32-bit architectures, the new calculation causes a build failure:
ld.lld-21: error: undefined symbol: __aeabi_uldivmod
Since neither value is ever larger than a register, cast both
sides into a uintptr_t.
Fixes: 5c03f9f4d362 ("watchdog: aspeed: Update bootstatus handling")
