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.
