cpufreq: qcom-cpufreq-nvmem: fix reading of PVS Valid fuse 



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.
