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.

This patch adds support for MCF SOC performance
monitoring in the driver. MCF SOC has two different
types of perfmuxes connected to the same perfmon:
one is the OCU type and the other is IBHX and OBHX.
IBHX is only accessible via MC16 aperture. Therefore,
this patch adds two separate IPs: OCU and IOBHX.
However, both are tied to the MCF SOC perfmon (mcfsoc0).

This patch adds support for C-NVLINK performance
monitoring in the driver. C-NVLINK consists of
RX, TX, and CTRL apertures, each with its own
perfmux signals and perfmons. So this patch
breaks them up into three sets of perfmux-perfmon
data structures.

- HALs get_rtr_int_idx and get_ip_max_idx return the chip specific
router index and number of IPs. This information is static for a chip
and doesn't require any input. Hence, update the HAL definition to not
require hwpm pointer as an argument. Update definition and references
for these HALs.
- Add new HAL to get PMA and RTR structure pointers. Implement and
update other chip specific functions to use new HAL.
- Add new timer macro to check a condition and timeout after given
retries. Update necessary code to use new timer macro.
- Correct validate_emc_config function to compute correct available mss
channel mask based on fuse value.
- Update tegra_hwpm_readl and tegra_hwpm_writel macros to assert error
value. This way error checks are added at one spot and not sprinkled all
over the driver code.
- Update get_mem_bytes_put_ptr() and membuf_overflow_status() to return
error as function return and accept arguments to return mem_head pointer
and overflow status respectively. Add overflow status macros to use
throughout driver. Update HAL definition and references accordingly.
- conftest is only compiled for OOT config atm. Add OOT config check to
include conftest header.
