Currently, HWPM driver checks regops address to validate that the
address belongs to an IP allowlist that is reserved for profiling.
However, it is possible that the allowlist doesn't include all register
offset that are required for profiling. This scenario is often
encountered during early stages of bringup. This patch adds a debugfs
node to make HWPM driver skip allowlist check. This change will allow
users to dynamically skip allowlist check when debugfs is available.

This patch fixes issues found during testing
and guidance provided by devtools. The following
is changed in this patch:
1. mcf_iobhx and mcf_ocu are merged into a single mcf_soc IP.
2a. c2c is changed from 2 instances to 1.
2b. Remove C2CS0/1 which are the broadcast apertures.
Also remove the allowlist offset specific to broadcast
aperture.
3. mss_hub is changed from 1 instance to 8.
4. mss_channel is changed from 1 instance to 32.
5. mc0 perfmux is added to mcf_clink.
6. mcf_core is changed from 1 instance to 8.
7. License headers updated where necessary.
8. c2c allowlist updated to have just the offsets common
to all links.
9. Added a verbose comment explaining the design of
th500_hwpm_force_enable_ips()
10. Added back validate_current_config module parameter
as many systems still don't support fuses.
11. If all F's are read back for a regop in ip_readl(),
return -ENODEV.
There is a corresponding patch to update the python scripts
that generated many of the C and header files.
