gpu: nvgpu: De-linuxify pmgr code

Browse Source 
The pmgr code is in theory common code. However there were uses
of Linux stuff within this code.

This patch cleans that up by deleting the unnecessary os_linux.h
includes, usage of kfree() and adds several platform fields to
the gk20a struct. The platform data is copied to the gk20a struct
in the platform initialization code so that this common code can
access said data without requiring any knowledge of the OS platform
data.
