Shortcomings of ALIGN macros:
- ALIGN_MASK down aligns when there is an wrapping/overflow instead of
throwing an error. This can affect the size assumptions.
- Alignment a's check will be bypassed when ALIGN_MASK is directly
used.
Fix these issues by 1) adding compile time error for non-unsigned type
arguments 2) using unsigned type safe ops for addition and subtraction.
Also, change users of ALIGN to pass unsigned types only.

In case of FBPA we need to consider mask of active FBPAs on dGPUs.
For that we have GR unit HAL g->ops.gr.add_ctxsw_reg_pm_fbpa()
Generic support to consider active mask of unit need not be in a HAL,
move it to common code in add_ctxsw_buffer_map_entries_subunits() itself
This API now supports providing active_unit_mask as its parameter
In case we don't need to consider unit mask caller will simply pass
~U32(0U) to indicate all units are active
In case of FBPA, add a new HAL g->ops.gr.hwpm_pm.get_active_fbpa_mask()
which gets mask of active FBPAs, and pass this value to common API
add_ctxsw_buffer_map_entries_subunits()

Create a new HAL unit hal.gr.hwpm_map that provides chip specific
support to common.gr.hwpm_map unit
We currently have common.gr HAL g->ops.gr.add_ctxsw_reg_perf_pma()
to handle chip specific alignment of perf_pma list
We only adjust the offset of list and remaining code is same
Hence delete above HAL, and add new HAL under hal.gr.hwpm_map
g->ops.gr.hwpm_map.align_regs_perf_pma() which returns correct
alignment if HAL is defined
Remove gr_gv100_add_ctxsw_reg_perf_pma() and
gr_gk20a_add_ctxsw_reg_perf_pma() APIs since they are no longer used
Simplify perf_pma parsing by fixing alignment with new HAL and then
directly calling add_ctxsw_buffer_map_entries()
