Vedashree Vidwans 913f1b0697 tegra: hwpm: add checks for PMA quiesce state
- Zeroing of PMA trigger registers is unnecessary. Remove corresponding
logic from HWPM teardown function.
- During device open, add a check for PMA/RTR status. This will ensure
that PMA/RTR are ready to start new profiling session. Device open will
fail if RTR and PMA enginestatus is not ready(idle).
- SOC HWPM driver disables and releases all reserved IPs before teardown
steps. Update teardown logic to zero out IP allowlist registers during
teardown.
