devfreq: Do not round up bandwidth on BWMON4 devices



Currently only BWMON5 devices increment the count for non-zero
bandwidth while BWMON4 devices increment the count all the time.
This results in a non-zero bandwidth report even when the count
is zero for BWMON4 devices leading to unnecessarily higher
bandwidth votes. Apply checks similar to BWMON5 devices for BWMON4
monitors as well.
