media: vimc: Ensure that pixel_rate fits in 32 bits

Browse source

pixel_rate is set to VIMC_PIXEL_RATE_FIXED, which the code expects to
fit in 32 bits. Make that constraint into a WARN_ON, so if we ever break
that constraint a kernel warning will be triggered.

It also fixes the following cocci warning:
./test-drivers/vimc/vimc-sensor.c:107:1-7: WARNING: do_div() does a 64-by-32 division, please consider using div64_u64 instead.
