- 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

Move chip specific code to chip specific folder. This will allow
multiple chip support in the future.
Create new specific functions
- Initialize hwpm structures
- Reserve and release PMA and RTR apertures
- Zero, update and check allowlists
- Set and get fake registers for MC aperture on simulation
- perfmon dt aperture enums

IP perfmon base address value is determined by iomap(). This iomap
address is dependent on many factors like platform, carveout, etc.
Currently, soc hwpm user passes static perfmon addresses to execute
reg ops.
Modify hwpm_resource_aperture struct to hold absolute/static start and
end address of the aperture. These new variables will indicate absolute
register range of the aperture.
Modify reg ops ioctl to determine aperture of given phys addr based on
IP's absolute register range.
