Make mc-hwpm module oot. Below are the reasons why
making a fresh copy in nvdia-oot folder -
- hwpm is introduced from T234 onwards
- mc-hwpm is dependent on mc driver. nvidia-oot
uses upstream mc driver. Hence mc-hwpm should also
use upstream mc driver.
- Thats why porting changes needed in mc-hwpm driver
to be incompatible with upstream mc driver

Port the downstream nvpmodel driver to the OOT project.
The following items summarize the change:
- Original bwmgr APIs are removed
- Clock cap for other clocks except for EMC is removed since userspace
nvpmodel service will handle clock cap for other clocks

Also, remove other failing nvhost functions as the nvhost driver

in linux below patches remove the support for QUEUE_FLAG_DISCARD
and QUEUE_FLAG_SECERASE.
commit 70200574cc229f6ba038259e8142af2aa09e6976
Author: Christoph Hellwig <hch@lst.de>
Date: Fri Apr 15 06:52:55 2022 +0200
block: remove QUEUE_FLAG_DISCARD
Just use a non-zero max_discard_sectors as an indicator for discard
support, similar to what is done for write zeroes.
The only places where needs special attention is the RAID5 driver,
which must clear discard support for security reasons by default,
even if the default stacking rules would allow for it.
commit 44abff2c0b970ae3d310b97617525dc01f248d7c
Author: Christoph Hellwig <hch@lst.de>
Date: Fri Apr 15 06:52:57 2022 +0200
block: decouple REQ_OP_SECURE_ERASE from REQ_OP_DISCARD
Secure erase is a very different operation from discard in that it is
a data integrity operation vs hint. Fully split the limits and helper
infrastructure to make the separation more clear.

The ivc.h is not protected for multiple inclusion and so
it is generating error for multiple definition when included
from the source code.
Add wrapper header to protect the multiple inclusion of the ivc.h.
This will make the OOT driers to compile against all core kernel
which does not have proper ivc.h fix.

The function __exit cleanup_module() references a function __init

to remove the __init annotation of tegra_hv_cleanup() so it may be

Using this patch we are doing below activities:-
1. Use as much as possible source code possible from
upstream driver.
2. If there is static function that needs to be exported
to downstream driver then make a local copy of that.
3. add support for extended ivc driver since upstream
driver does not have support for all required APIs.

Sequencer. Driver depends on CONFIG_MFD_NVVRS_PSEQ to get enabled which
is a parent driver for RTC. Following are the VRS RTC functionalies:
1. RTC executes alarm function to wake system from suspend/shutdown state.
2. RTC has 32bit time counter register which increments each second.
3. RTC triggers interrupt when the set alarm time becomes equal to the time
read from TIME registers.
