gpu: nvgpu: ga10b: update pri_hub and ptimer error handling

Replace ga10b_ptimer_isr with gk20a_ptimer_isr.

Remove GPU_PRI_ACCESS_VIOLATION reporting from gp10b hal as only
ga10b should be reporting these errors.

GPU_PRI_TIMEOUT_ERROR was only reported from ptimer ISR. However,
it is to be reported when error code is 0xbadf10xx that can be
seen through priv_ring ISR as well. Hence report this error
from ga10b_priv_ring_decode_error_code called from both bus
and priv_ring isr.

For other error cases GPU_PRI_ACCESS_VIOLATION is reported.

Other updates for priv_ring error handling are given below:

1. Add extra info decode functions for error codes:
 - 0xbad001xx, 0xbad002xx, 0xbad0daxx - decode_host_pri_error
 - 0xbadf13xx - decode_fecs_floorsweep_error
 - 0xbadf24xx, 0xbadf25xx, 0xbadf26xx - decode_gcgpc_error &
					decode_pri_local_decode_error
 - 0xbadf20xx, 0xbadf22xx - decode_fecs_pri_orphan_error
 - 0xbadf52xx - decode_pri_indirect_access_violation
 - 0xbadf60xx - decode_pri_lock_sec_sensor_violation

2. Add more info prints to decode_pri_falcom_mem_violation.

3. Add entry for extra info corresponding to 0x41 to
pri_client_error_extra_4x.

4. Separate extra info decode function for error 0xbadf50xx.
