Deepak Nibade 7158db453c gpu: nvgpu: add test offsets to allowlist
Add ptimer register offsets to regops allowlist for testing. New
allowlist restricts regops only to reserved resources, this makes it
difficult to test the interface since only HWPM registers can be
accessed and that could have side effects on system.

Having ptimer registers as test offsets has advantage that the offsets
do not change across chips, registers are read-only, and values are
always incrementing so a test can verify read regops and test various
flags of interface.

Add gops.ptimer.get_timer_reg_offsets() HAL to return timer offsets.

Add static function add_test_range_to_map() that adds timer offsets to
allowlist always.

In nvgpu_profiler_validate_regops_allowlist() return success if timer
offsets are hit in range search.
