tegra: hwpm: update logic to use static indexes

Browse Source 
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.
