fe7a4734a2 tegra: hwpm: update IP registration interface
Enum tegra_soc_hwpm_ip is defined to query IP information. To untangle
its use from HWPM related functionality, enum tegra_soc_hwpm_resource
should be used by IP drivers to register with HWPM.

An IP can have multiple instances with multiple IP core elements in
each instance. Currently, the IP <-> HWPM register access API passes
register offset only. However, it is not possible to figure out
requested specific register access only with register offset. For
example, MC device has one instance with 16 duplicate channels. To
access channel x perfmux register, HWPM driver should pass perfmux
register offset alongwith channel number (index).
Add instance element index as an argument to the register access API,
tegra_soc_hwpm_ip_ops.hwpm_ip_reg_op().
-Update internal copy of tegra_soc_hwpm_ip_ops.
-Update hwpm_ip_reg_op() implemented in flcn driver.
-Update hwpm_ip_reg_op() implemented in pva driver.

Update hwpm_ip_pm() in flcn driver to use nvhost power management APIs.

3b6a1b35b7 tegra: hwpm: update basic structure layout
Introduced macros to define HWPM aperture types perfmon, perfmux and
broadcast.
Added new enum to define element type.
IP perfmux and IP broadcast are handled in similar way. Whereas, HWPM
perfmux should use HWPM perfmon functions.

Updated hwpm structures are as below
Parent HWPM structure
  -> Active chip structure
     -> Array of IPs
     -> HALs

IP structure
  -> Array of instances
  -> Array of instance info with respect to perfmon, perfmux, broadcast
  -> Instance mask : indicates available instances
  -> reserved status

Instance structure
  -> Array of element info with respect to perfmon, perfmux, broadcast
      -> Array of corresponding element structures
  -> Element mask : indicates available elements in the instance

Element structure
  -> Aperture address details
  -> DT node / MMIO details

Update all functions to use new HWPM structures.

Update hwpm_probe to include force IP enable step.

25f0737897 tegra: hwpm: combine common functionality
- Many HWPM functions are performed on all apertures of all instances of
all IPs. Define below resource utility functions to perform a task on
all IPs, instances and apertures:
  - tegra_hwpm_func_all_IPs
  - tegra_hwpm_func_single_ip
  - tegra_hwpm_func_all_instance
  - tegra_hwpm_func_single_instance
  - tegra_hwpm_func_all_perfmuxes
  - tegra_hwpm_func_all_perfmons
  - tegra_hwpm_func_single_aperture
- Modify below functions to use above mentioned utility functions:
  - get allowlist size
  - combine allowlist
  - reserve resources
  - bind resources
  - release resources

This will make code more legible and maintainable.

This patch also defines new function that validates all HAL
initializations for the chip.

ea5e4e406b tegra: hwpm: add HALs to support multiple chip
Add below HALs to make code chip agnostic. This will allow us to use
t234 specific HALs for next chips.
- get_pma_int_idx: get PMA's internal index corresponding to active chip
- get_rtr_int_idx: get RTR's internal index corresponding to active chip
- get_ip_max_idx: get MAX IP index corresponding to active chip

Move chip agnostic code to common files.
