gpu: nvgpu: Cleanup GMMU debug printing
Ensure that all debug prints are consistent from chip to chip
and function to function. The following maps letters in the
debug print to their meaning:
C Mapping is cachable
v Mapping is volatile
S Mapping is sparse
P Mapping is private (VPR/WPR)
c Mapping is coherent
V Mapping is valid
