drm/i915/bw: Fix DEPROGBWPCLIMIT handling on BMG
DEPROGBWPCLIMIT is specified in %, so divide by 100 instead of 10.
Fortunately the deprobbwlimit is much lower than the peak memory
bandwidth on BMG, so whether we take 60% or 600% of the peak
bandwidth doesn't matter as the min() will pick the lower
deprobbwlimit anyway.
Eg. on the BMG here I get (with or without the fix):
QGV 0: deratedbw=33600 peakbw=48000
QGV 1: deratedbw=53000 peakbw=456000
