intel_pstate: set BYT MSR with wrmsrl_on_cpu()
Commit 007bea098b86 (intel_pstate: Add setting voltage value for baytrail P states.) introduced byt_set_pstate() with the assumption that it would always be run by the CPU whose MSR is to be written by it. It turns out, however, that is not always the case in practice, so modify byt_set_pstate() to enforce the MSR write done by it to always happen on the right CPU. Fixes: 007bea098b86 (intel_pstate: Add setting voltage value for baytrail P states.)
