For MSS channel, hwpm client expects floorsweep info mask to indicate
available MSS chanenel perfmuxes.
HWPM driver would prefer to follow common fs_mask logic for IPs and is
being discussed.
Temporarily update floorsweep info logic for MSS channel, until
floorsweep info IOCTL modifications are finalized.

- 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
