[RFC][PVR] Make use of CLog::LogF

I was bored so this was my tedious afternoon work. Didn't compile/runtime checked since I'm away from my main machine and compiling in a C2D isn't fun anymore, specially since I don't have an env prepared.
Long live Atom for helping bored people be productive.

This is the first of a set of PRs to uniformize logs and migrate to CLog::LogF

@opdenkamp, @Jalle19, @xhaggi and others interested for review/comment.

Have a great one! Don't split, squash!
