[Why]
Currently, the clk manager matches SocVoltage with voltage from
fused settings (dfPstate clock table). And then corresponding clocks
are selected.
However in certain situations, this leads to clk manager not
including at least one entry with highest supported clock setting.
[How]
Update the clk manager to include at least one entry with highest
supported clock setting.

This will let us pass the kms_hdr.bpc_switch IGT
test.
The reason the bpc restriction was required is
historical. At one point in time we were not falling
back to a lower bpc when we didn't have enough
bandwidth for the maximum bpc reported by a display.
This meant that we couldn't enable some high refresh
modes unless we limitted the bpc.
Starting with this patch the issue is fixed:
commit cbd14ae7ea ("drm/amd/display: Fix
incorrectly pruned modes with deep color")
This patch implemented a fallback mechanism if mode
validation failed at the max bpc. This means users
now automatically get all modes that can be supported
by at least 6 bpc. The driver will enable the mode
with the highest possible bpc that is supported by
the display.
v2:
- explain why this is no longer needed (Michel)
- refer to commit that fixed bpc fallback (Michel)

[Why&How]
Temporarily disable SubVP+DRR since Xorg has an architectural limitation
where freesync will not work in a multi monitor configuration. SubVP+DRR
requires that freesync be working.
Whether OS has variable refresh setting enabled or not, the state on
the crtc remains same unless an application requests VRR. Due to this,
there is no way to know whether freesync will actually work or not
while we are on the desktop from the kernel's perspective.
If userspace does not have a limitation with multi-display freesync (for
example wayland), then this feature can be enabled by adding a
dcfeaturemask option to amdgpu on the kernel cmdline like:
amdgpu.dcfeaturemask=0x200

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.

[why]
A recent change was made to implement temporary workaround due DRM
update in MST interfaces. The workaround is added into our generic
deallocation MST sequence.
This ticket is to extract this temporary workaround into its own function so
it is differentiated from our generic sequence.

[Why]
In disable_dangling_plane, for phantom pipes, we enable OTG so
disable programming gets the double buffer update. But this
causes an underflow to occur.
[How]
Enable DPG prior to enabling OTG.
