gpu: nvgpu: Changed enum gmmu_pgsz_gk20a into macros

Changed the enum gmmu_pgsz_gk20a into macros and changed all the
instances of it.

The enum gmmu_pgsz_gk20a was being used in for loops, where it was
compared with an integer. This violates MISRA rule 10.4, which only
allows arithmetic operations on operands of the same essential type
category. Changing this enum into macro will fix this violation.
