a23d954e3e platform: dce: Add bootsrap2 command
Add support to the bootstrap command over the admin channel,
which will be called when a client registers. This command will
perform steps that must be performed only after the client is ready.

TODO: This bootstrap-2 command will be replaced by the existing
bootstrap command which we call during DCE-FW bootstrapping once
we split admin bootstrapping and RM bootstrapping in the DCE-KMD.

d7a9c5b734 dce: update for mods test
DCE FW will run the dma test using 512 bytes of transfer
between dram and tcm for 400 iterations and alu test
generating 100 prime numbers for 200 iterations.
DCE running above 600Mhz will take nearly 50msec
for each test.

3c473c60eb platform: dce: set MIT license for dce headers
Change NV license for dce headers to MIT license as those
can be distributed with other linux sources but they are also
used in DCE firmware.

606f03fbf2 platform: tegra: dce: add dce kernel driver
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
