Previously, the syfs functionality for restoring the default powerplay
table was sourcing it's information from the currently-staged powerplay
table.

This patch adds a step to cache the first overdrive table that we see on
boot, so that it can be used later to "restore" the powerplay table

[Why]
When we disable a connector we don't explicitly remove it from the module so the
display is still cached(SW) in the hdcp_module.

SST: no issues because we can only have 1 display per link

MST: We have x displays per link, now if we disable 1 we don't remove it from the
module so the module has x display cached(SW).

If we try to enable HDCP, psp verification will fail because we are reporting x
displays while the HW only has x-1 display enabled

[How]
Check the callback for when we disable stream and call remove display.

The sdma_queue_count increment should be done before
execute_queues_cpsch(), which calls pm_calc_rlib_size() where
sdma_queue_count is used to calculate whether over_subscription is
triggered.

With the previous code, when a SDMA queue is created,
compute_queue_count in pm_calc_rlib_size() is one more than the
actual compute queue number, because the queue_count has been
incremented while sdma_queue_count has not. This patch fixes that.

[Why]
In current code we're essentially drawing the cursor on every pipe
that contains it. This only works when the planes have the same
scaling for src to dest rect, otherwise we'll get "double cursor" where
one cursor is incorrectly filtered and offset from the real position.

[How]
Without dedicated cursor planes on DCN we require at least one pipe
that matches the scaling of the current timing.

This is an optimization and workaround for the most common case where
the top-most plane is not scaled but the bottom-most plane is scaled.

Whenever a pipe has a parent pipe in the blending tree whose recout
fully contains the current pipe we can disable the pipe.

This only applies when the pipe is actually visible of course.

[WHY]
Two years ago the patch referenced by the Fixes tag stopped running
dp_verify_link_cap_with_retries during DP detection when the reason
for the detection was a short-pulse interrupt. This effectively meant
that we were no longer doing the verify_link_cap training on active
dongles when their SINK_COUNT changed from 0 to 1.

A year ago this was partly remedied with:
commit 80adaebd ("drm/amd/display: Don't skip link training for empty dongle")

This made sure that we trained the dongle on initial hotplug (without
connected downstream devices).

This is all fine and dandy if it weren't for the fact that there are
some dongles on the market that don't like link training when SINK_COUNT
is 0 These dongles will in fact indicate a SINK_COUNT of 0 immediately
after hotplug, even when a downstream device is connected, and then
trigger a shortpulse interrupt indicating a SINK_COUNT change to 1.

In order to play nicely we will need our policy to not link train an
active DP dongle when SINK_COUNT is 0 but ensure we train it when the
SINK_COUNT changes to 1.

[HOW]
Call dp_verify_link_cap_with_retries on detection even when the detection
is triggered from a short pulse interrupt.

With this change we can also revert this commit which we'll do in a separate
follow-up change:
commit 80adaebd ("drm/amd/display: Don't skip link training for empty dongle")
