- Rename dce-os-device to dce-linux-device
- dce-os-device.h header is specific to OS and is only intended
to be internally used within OS. Similarly all it's exposed
functions are OS specific only.
- Therefore instead of having a common name for all OSs for this
header file, make this header internal by including linux
name to it's naming convention.
- Similary rename dce_os_device struct to dce_linux_device and
also rename corresponding functions from this header.

Modules covered in this CL:
1) dce-os-log
This is not a functional CL. It does the following:
1) Rename dce_<info/err/debug/warn> to
dce_os_<info/err/debug/warn>
2) Rename dce_log_msg() to dce_os_log_msg()
3) Rename DCE_<WARNING/ERROR/INFO/DEBUG> to
DCE_OS_<WARNING/ERROR/INFO/DEBUG>
4) Move dce-log.h to os/linux/include/dce-os-log.h
5) Stop using old abstraction:
a) Replace <os-dce-log.h> includes with <dce-os-log.h>
6) Delete all related old deprecated log files:
a) os/include/linux-kmd/os-dce-log.h
b) os/include/os-dce-log.h

- In DCE_KMD, dce_fsm_start() schedules start of state machine
functionality which involves the waiting for DCE-FW boot completion,
IPC admin setup and communication etc.
- HVRTOS restricts certain functionalities like waiting on events,
acquiring locks, etc in initialize phase.
- Also for HVRTOS we are executing worker queue work in same
thread context directly from where it's called from.
- For above reasons, we need to decouple SW resource allocation and
init logic and actual execution start logic which was part of
dce_driver_init() earlier into 2 phases:
- dce_driver_init()
- This will do all resource allocation/init and will be called
during resource initialization phase.
- Module probe for Linux
- Initialize() context for HVRTOS.
- dce_driver_start()
- This will start actual DCE logic execution after all
resources are allocated and initialized and will be executed
separately.
- In Linux, both will be executed from the same probe
while in HVRTOS, the former is in process initialize
stage and dce_driver_start is run in the
Thread initialize stage.

For Linux v6.8, commit ef175b29a242 ("of: Stop circularly including
of_device.h and of_platform.h") updated the OF headers included by these
header files. This breaks the build for various drivers and so fix this
by including the headers that are actually needed for each driver.

Once DCE suspend is called it disables the DCE controller
later DCE controller can be brought out of reset only by MB2RF,
But if after dce suspend due to any reason system suspend fails, mb2rf
will not be called. And the display will not work.
This patch makes DCE suspend a late suspend. So, it reduces the race
condition window.

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)
This patch puts a framework in place with the
following features :
1. Firmware Loading
2. AST Configuration
3. DCE Reset with EVP Programming
4. Logging Infra
5. Debugfs Support
6. Interrupt Handling
7. Mailbox Programming
8. IPC Programming
9. DCE Client Interface
10. Ftrace Support for debug purposes
