tegra: hwpm: fix bugs on ToT

Browse Source 
- With latest changes, disable PMA triggers contained a bug related to
timeout checks. Reading register value in while loop was removed
accidentally.
Replace HWPM_TIMEOUT macro with do-while loop to check condition.
- Correct func enum used to release router.
- Correct MSS MCF IP and instance address stride.
