[ Upstream commit 4a8a77abf0e2b6468ba0281e33384cbec5fb476a ]
The fuse consists of 64 bits, with this statement we're supposed to get
the upper 32 bits but it actually read out of bounds and got 0 instead
of the desired value which lead to the "PVS bin not set." codepath being
run resetting our pvs value.
Fixes: a8811ec764f9 ("cpufreq: qcom: Add support for krait based socs")
