[Why]
We only allowed 1 overlay plane. But now some ASICS can support multiple
overlay planes.
[How]
Use max_slave_planes as the number of overlays we can support.
Also since we cannot draw cursor over a video plane, we need to make
sure that we reject commits where the topmost plane is a video plane
(overlay only).

[why]
Link is a subcomponent in dc. DM should be aware of dc link structure
as one of the abstracted objects maintained by dc. However it should
have no idea of the existence of a link component in dc dedicated to
maintain the states of dc link structure. As such we are moving link interfaces
out of dc_link.h and directly added to dc.h. We are grandually fading out
the explicit inclusion of dc_link header and eventually delete it.
On dc side, since link is a subcomponent behind dc interfaces, it is not
a good idea to implement dc interfaces in each individual subcomponent
of link which is already a subcomponent of dc. So we are decoupling it
by implementing a dc_link_exports in dc. This file will be a thin
translation layer that breaks the dependency so link is able to make
interface changes without breaking DM.

HUBP_UNBOUNDED_REQ_MODE being enabled while the display is rotated (eg.
going from Portrait mode to Landscape mode) appears to be causing a
p-state hang, specifically during full screen mode on the Tiktok PC app.
Unbounded request mode doesn't appear to be supported with rotation
configs, hence disabling it.
[how]
Within DML, modified unbounded request mode to be configured only when
the rotation angle of the plane is 0.

Newer ASICs such as DCN314 needs to allow for both self refresh and mem
clk switching rather than just self refresh only. Otherwise, we can see
some p-state hangs on ASICs that do support mem clk switching.
[how]
Added an allow_self_refresh_only flag for dcn30_internal_validate_bw
and created a validate_bw method for DCN314 with the allow_self_refresh_only
flag set to false (to support mem clk switching).

We mistakenly toggle dpms state for non master pipe when handling
link lost. A non master pipe doesn't connect to a backend. So it is
toggling dpms for non master is undefined and caused NULL pointer
dereference.
[how]
Add helper functions to find an array of active master pipes for current
link and only toggle DPMS for active master pipes connected to the link.
Add assert in case we get called to program dpms with non master pipe.

[Why]
DOMAIN power gating control is now required to be done via firmware
due to interlock with other power features. This is to avoid
intermittent issues in the LB memories.
[How]
If the firmware supports the command then use the new firmware as
the sequence can avoid potential display corruption issues.
The command will be ignored on firmware that does not support DOMAIN
power control and the pipes will remain always on - frequent PG cycling
can cause the issue to occur on the old sequence, so we should avoid it.

Some users have reported flickerng with S/G display. We've
tried extensively to reproduce and debug the issue on a wide
variety of platform configurations (DRAM bandwidth, etc.) and
a variety of monitors, but so far have not been able to. We
disabled S/G display on a number of platforms to address this
but that leads to failure to pin framebuffers errors and
blank displays when there is memory pressure or no displays
at all on systems with limited carveout (e.g., Chromebooks).
We have a parameter to disable this as a debugging option as a
