gpu: nvgpu: switch gk20a nonstall ops to #defines

Fix MISRA rule 10.1 violations involving gk20a_nonstall_ops
enums by replacing them with with corresponding #defines.

Because these values can be used in expressions that require
unsigned values (e.g. bitwise OR) we cannot use enums.

The g->ce2.isr_nonstall() function was previously returning an
int that was a combination of gk20a_nonstall_ops enum bits which
led to the violations.
