[PATCH 2/3] perf: use hweight64 instead of hweight_long

[Mao Han]

On C-SKY platform, there are 38 registers inside pt_regs. The same
layout is directly used by perf to keep uniformity. The mask is 64
bits, but hweight_long can only handle 32 bits, which will casue
perf.data analysis mismatch on C-SKY.
