Compression carveout is not correct carveout name as it will be used
by gpu even for non-compression usecases. Hence rename it to gpu
carveout.

OOT drivers build against multiple kernel. All kernel
does not support the prod configurations. Add wrapper
header for prod header as oot-prod which can be used
by all OOT drivers for prod configurations.
This new header implement the prod APIs as success if
core kernel does not support the prod functionality.
This will help to avoid any build and run time error.

By exporting cvnas_dev all the internal data of the driver is getting
exposed to any driver that uses it. This could allow drivers to corrupt
this driver data. Hence do not export cvnas_dev, use helper functions to
get it's required member elements from nvmap.

Handle dependencies between nvmap and cvnas driver:
- nvmap_register_cvsram_carveout function is called by cvnas driver
(builtin driver for 5.10) and it's definition is present in nvmap driver
(builtin driver for 5.10, but we are trying to make LKM). This is
resulting into build issues while making nvmap as LKM for 5.10
- One option to resolve this is by making cvnas driver as LKM for 5.10
But nvhost, nvdla, cbb are not LKM for 5.10 and are calling functions
defined in cvnas driver e.g. nvcvnas_get_cvsram_base, hence we can't
make cvnas as LKM for 5.10
- Second option is to get rid of the call nvmap_register_cvsram_carveout
from cvnas driver. This approach is implemented in this patch.
- Export cvnas_dev from cvnas driver, do not call the above function
from cvnas driver. During nvmap probe, nvmap itself would call the above
function, as cvnas_dev is exported , it's being used in nvmap driver to
get base, size etc. information, which is needed as argument to above
function, which will register the cvnas carveout in case of 5.10

There are a few problems here which are:
1. The CVNAS driver does not include the 'cvnas.h' header file and so
some of the declarations are not found.
2. Some of the CVNAS functions are not declared in the 'cvnas.h' header
file and need to be added.
3. The Tegra19x CBB driver is a user of these CVNAS functions, but
instead of including the 'cvnas.h' file it defines prototypes for
these functions. This is not necessary and so we can remove these
prototypes and simply include the 'cvnas.h' header file.
4. The function definition nvcvnas_idle_no_rpm() in the CVNAS driver is
incorrect and this function should not have any arguments passed to
it and currently does not match the prototype.

For T23x, we have a separate R5 based cluster
named as Display Controller Engine(DCE) to run
our Display RM code. This driver will run on CPU
with the following functionality:
Via debugfs for test and bring-up purposes:
1. Reads the DCE firmware image into DRAM.
2. Sets up DCE AST to cover the DCE firmware image.
3. Sets up R5 reset vector to point to DCE firmware
entry point
4. Brings DCE out of reset
5. Dumps various regsiters for debug
In production env:
1. Manages interrupts to CPU from DCE
2. Uses bootstrap command interface to define Admin
IPC
3. Locks down bootstrap command interface
4. Uses Admin IPC to define message IPC
5. Uses Admin IPC to define message IPC payload area
6. Uses Admin IPC to set IPC channels
6. Uses Admin IPC to define crashdump area
(optional)
7. Provides IPC interfaces for any DCE Client running
on CCPLEX including Display RM.
8. Uses Admin IPC to set logging level (optional)

1. Firmware Loading
2. AST Configuration
3. DCE Reset with EVP Programming
4. Logging Infra
5. Debugfs Support
6. Interrupt Handling
7. Mailbox Programming

The syncpt interface APIs in the host1x-nvhost driver slightly differ
from those in the legacy nvhost driver because instead of passing the
platform device structure for the host1x device, the platform device
structure for the host1x client device is passed.
By aligning the APIs so that we pass the platform device structure for
the host1x in all implementations, we can simplify the PVA driver and
directly use the APIs in the NVIDIA display driver.
The NVIDIA display driver requires some additional syncpt interface APIs
and so implement these as well.
