gpu: nvgpu: add errata NVGPU_ERRATA_3524791

Browse Source 
Update PES, ROP exception handling for NVGPU_ERRATA_3524791. Enable the
errata for all Volta+ chips.

ROP, PES exceptions are being reported using the physical-id,
where logical-id should have been used. All ESR status registers are
reported using logical-id, so this matches with the SW expectation.
To address the (1), update ROP, PES exception handler translate from
physical to logical-id before reading the status registers.
