Update pmu ucode version for next pmu to 29323513.
This version is taken from P4 CL#29323216.
Changes:
- Enabled ACR task support
- Disabled few features/code for commands to work
- ELPG fifo preemption hals fixed
- Halt functions in ELPG save and restore functions
are commented as bloaded flag is not getting set. This
is not significant as this change will not have any impact
in elpg functionality.

Add supper surface gpu_va details to super surface header member
as needed by PMU ucode to process.
This is required for iGPU PMU ucode on nvgpu-next to process command
line args and ACK back with INIT message, without this PMU ucode ends
up in hang due to DMA wait.
Update super-surface details to cmd line args for PMU ucode to
know the starting address of super-surface in SYSMEM.

Changes:
- Send down BOARDOBJGRP classId to the PMU. Assign each
BOARDOBJ the classId of its parent group which is set
to zero in current implementation. Changed in NVGPU to send
board obj grp classid to PMU.
- Disable IPC VMIN support as pmu-tu10a profile doesn't support.
- Change in clk vf point enumeration types.
- Change in pstate type values.
- Updated ctrl_perf_vfe_var_single_sensed_fuse_ver_vfield_info
NVGPU-PMU interface struct with b_ver_expected_is_mask to send
whether the expected version is single value or should be
interpreted as a bit mask with bits corresponding to

Current clk unit has multiple header files under pmuif folder.
This has combination of public struct which is accessed outside the
unit and private struct which is accessed within clk unit.
This patch segregates them based on their accessibility.
All private items are moved into ucode_clk_inf.h from pmuif which only
clk can access.
All public items are moved into include/clk.h which other units can
access
This will help in documentation of items for public items.

PMU IRQs were not enabled assuming entire functionality for LS PMU.
Debugging early init issues of PMU falcon ECC errors triggered
during nvgpu power-on will be cumbersome if interrupts are not
enabled early. FMEA analysis of the nvgpu init path also
requires this interrupt be enabled earlier.
Hence, Enable the PMU ECC IRQ early during nvgpu_finalize_poweron.
pmu_enable_irq is updated to enable interrupts differently for
safety and non-safety. PMU interrupts disabling is moved out
of nvgpu_pmu_destroy to nvgpu_prepare_poweroff. Prepared new
wrapper API nvgpu_pmu_enable_irq.
PMU ECC init and isr mutex init is moved to the beginning of
nvgpu_pmu_early_init as for safety, ls pmu code path is
disabled. Fixed the pmu_early_init dependent and mc
interrupt related unit tests.
Update the doxygen for changed functions.

A call to exit the PMU state machine/kthread must
be prioritized over any other state change.
It was possible to set the state as PMU_STATE_EXIT,
signal the kthread and overwrite the state before
the kthread has had the chance to exit its loop.
This may lead to a "lost" signal, resulting in
indefinite wait during the destroy sequence.
Faulting sequence:
1. pmu_state = PMU_STATE_EXIT in nvgpu_pmu_destroy()
2. cond_signal()
3. pmu_state = PMU_STATE_LOADING_PG_BUF
4. PMU kthread wakes up
5. PMU kthread processes PMU_STATE_LOADING_PG_BUF
6. PMU kthread sleeps
7. nvgpu_pmu_destroy() waits indefinitely
This patch adds a sticky flag to indicate PMU_STATE_EXIT,
irrespective of any subsequent changes to pmu_state.
The PMU PG init kthread may wait on a call to
NVGPU_COND_WAIT_INTERRUPTIBLE, which requires a
corresponding call to nvgpu_cond_signal_interruptible()
as the core kernel code requires this task mask to
wake-up an interruptible task.

Right now in PMU we have disabled usage of VFE cached values
as we have seen failures in 5.1.3.0 release. This patch
will send vfe_var dependent masks to PMU which will be
used for initial invalidation of dependent VFE_VAR cached
values. As a result PMU will compute the dependent VARs and
cache them.
