PM: Use a more common logging style

Convert printks to pr_<level>.

Miscellanea:

o Use pr_fmt with "PM:" and remove "PM: " from format strings
o Coalesce format strings and realign format arguments
o Convert an embedded incorrect function name to "%s: ", __func__
o Convert a couple multi-line formats to multiple pr_<level> calls
