- 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.

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.

- Update HWPM driver to add HAL layer. This will allow support for multiple chips.
- Add below data structure hierarchy for HWPM driver
HWPM driver structure -> chip info struct -> ip info array -> perfmux/perfmon info array
NOTE: To make commit message more legible, using "aperture" instead of "perfmux and/or perfmon"
- Chip info structure contains
- Array of IP info
- HAL function pointers
- IP info structure contains IP specific info
- Number of instances
- Number of apertures per instance
- Aperture ranges, strides, static info array
- Aperture dynamic arrays
- Aperture info structure contains
- Hw index
- Physical address info
- MMIO address info
- Add separate IP info files
- Create separate files that include logic for allowlist, memory buffer, resources, ip, regops to make functions more legible.
- Move probe, ioctl and io functions to os/linux path.
- Add fn, info, register and verbose debug log levels to controls debug messages
- add debugfs node to update dbg_mask
- Correct MGBE perfmux base address
