Fix the shift value for incorporating element fs
mask to the final IP floorsweeping mask.
The floorsweeping info contains the fs info
of all the elements in the IP. The patch fixes
an issue for IP with more than two instances,
where the element fs info of 3rd instance
onwards are not calculated correctly.

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.

HWPM driver uses nested structures and arrays of structures. The IP
structure setup logic allocates pointer arrays based on dynamic list of
IPs and aperture addresses. This dynamic list is required to search
given regops address in less amount of time.
However, there is a chance that the number of pointers computed
dynamically is huge. And huge amount of memory will be required for the
dynamic pointers array, which is impractical.
This, this patch modifies ip structure setup and address to aperture
conversion logic to use static indexes if the pointer array size is
huge.
This patch modifies relevant functions to always use static arrays
to access instance and aperture structures.
If dynamic pointers array is allocated, the patch adds logic to
translate dynamic index to static index using inst_index_mask for
instances and new added aperture_index for element level structures.
Add/update few log message to improve relayed information.

- 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.
