[PATCH v2] media: venus: fix build on 32bit environments

[Mauro Carvalho Chehab]

As reported by jenk...@linuxtv.org, the build with i386 fails
with:

        ld: drivers/media/platform/qcom/venus/helpers.o: in function 
`venus_helper_load_scale_clocks':
        (.text+0x1d77): undefined reference to `__udivdi3'
        ld: (.text+0x1dce): undefined reference to `__udivdi3'
        make: *** [Makefile:1094: vmlinux] Error 1

That's because it divides an u32 bit integer by a u64 one.

Fix it by explicitly callind do_div.
