Null pointer dereference issue could occur when pipe_ctx->plane_state
is null. The fix adds a check to ensure 'pipe_ctx->plane_state' is not
null before accessing. This prevents a null pointer dereference.

All dce command_table_helper's shares a copy-pasted collection
of copy-pasted functions, which are: phy_id_to_atom,
clock_source_id_to_atom_phy_clk_src_id, and engine_bp_to_atom.
This patch removes the multiple copy-pasted by moving them to
the command_table_helper.c and make the command_table_helper's
calls the functions implemented by the command_table_helper.c
instead.

[Why]
Transitioning from low to high resolutions at high refresh rates caused grey corruption.
During the transition state, there is a period where plane size is based on low resultion
state and ODM slices are based on high resoultion state, causing the entire plane to be
contained in one ODM slice. DML2 would turn off the pipe for the ODM slice with no plane,
causing an underflow since the pixel rate for the higher resolution cannot be supported on
one pipe. This change stops DML2 from turning off pipes that are mapped to an ODM slice
with no plane. This is possible to do without negative consequences because pipes can now
take the minimum viewport and draw with zero recout size, removing the need to have the
pipe turned off.
[How]
In map_pipes_from_plane(), remove "check" that skips ODM slices that are not covered by
the plane. This prevents the pipes for those ODM slices from being freed.

[WHY]
Previously the 128b/132b LTTPR support DPCD field was used to decide if
FIXED_VS training sequence required a rate toggle before initiating LT.
When running DP2.1 4.9.x.x compliance tests, emulated LTTPRs can report
no-128b/132b support which is then forwarded by the FIXED_VS retimer.
As a result this test exposes the rate toggle again, erroneously causing
failures as certain compliance sinks don't expect this behaviour.
[HOW]
Add new DPCD register defines/reads to read LTTPR IEEE OUI and device ID.
Decide whether to perform the rate toggle based on the LTTPR's IEEE OUI
which guarantees that we only perform the toggle on affected retimers.

[Why]
We must implement an ACPI re-timer programming interface and notify
ACPI driver whenever a PHY transition is about to take place.
Because some trace lengths on certain platforms are very long,
then a re-timer may need to be programmed whenever a PHY transition
takes place. The implementation of this re-timer programming interface
will notify ACPI driver that PHY transition is taking place and it
will trigger the re-timer as needed.
First we need to gather retimer information from ACPI interface.
Then, in the PRE case, the re-timer interface needs to be called before we call
transmitter ENABLE.
In the POST case, it has to be called after we call transmitter DISABLE.
[How]
Implemented ACPI retimer programming interface.
