From: Arnd Bergmann <arnd@xxxxxxxx>
In some randconfig builds, a 64-bit resource_size_t is used even on
32-bit architectures, which now leads to a link-time error:
ERROR: modpost: "__aeabi_uldivmod" [drivers/remoteproc/qcom_pil_info.ko] undefined!
Using the div_u64() helper here. A cast to 32 bits length would also
work, but for a constant divider there should not be much difference.
Fixes: 549b67da660d ("remoteproc: qcom: Introduce helper to store pil info in IMEM")
