tegra: hwpm: consider PMA as regular IP

Browse Source 
PMA and RTR perfmuxes contain registers required to configure HWPM.
So currently, PMA and RTR IPs are treated as special case and
initialized - released along with the driver.
However, as RTR IP includes both router and pma apertures, only treat
RTR as special IP. Change RTR config to have router and pma apertures
as separate instances. Define macros for router and pma instance index.
This will be allow to retrieve router and pma aperture structures.

Remove PMA IP reservation during driver init and PMA IP release at
driver close. As PMA IP is not treated special now,
remove get_pma_ip_idx() HAL.

Modify HWPM configuration functions to use router and pma apertures
initialized as part of RTR IP.
