[Why]
Previous patch to allow DTBCLK disable didn't address boot case. Driver
thinks DTBCLK is disabled by default, so we don't send disable message to
PMFW. DTBCLK is then enabled at idle desktop on boot, burning power.
[How]
Set dtbclk_en to true on boot so that disable message is sent during first
commit.

We need to re-enable idle power optimizations after entering PSR. Since,
we get kicked out of idle power optimizations before entering PSR
(entering PSR requires us to write to DCN registers, which isn't allowed
while we are in IPS).

Currently, with F32 HWS GPU reset is only when unmap queue fails.
However, if compute queue doesn't repond to preemption request in time
unmap will return without any error. In this case, only preemption error
is logged and Reset is not triggered. Call GPU reset in this case also.

We are boundling changes in plane state and build scaling params
together. This is to simplify DML code so DML doesn't need to build
scaling params. We are also avoiding rebuilding scaling params for
planes without scaling changes.

[why]
when ODM + MPO is used for all 4 available pipes. Pipe transition will
be nonseamless. Phantom OTG master pipe reuses the secondary OPP head
pipe. There is no possible seamless path to transit to the new
state. The correct logic would be to reuse a secondary DPP pipe as the
phantom OTG master pipe. This way we are able to first transit the
minimal transtion state of new and then transit to new state seamlessly.
current New (nonseamless)

[WHY]
Previously, we'd disabled HPO whenever an HPO display was disconnected. This
caused other HPO displays to blank whenever one was unplugged.
[HOW]
This change restricts HPO enable/disable to dce110_apply_ctx_to_hw and adds a
helper function (dce110_is_hpo_enabled) that returns true if any HPO displays
are present in a context. We compare the current and previous dc ctx to check
whether HPO is transitioning from on to off or vice versa, and adjust the HPO
state accordingly.

[Why & How]
There is a corner case where a single PSR panel
fails to enter idle optimizations if the panel
is not flipping (no planes or DPMS_OFF == true).
This is because the panel will not enter PSR if it's
not flipping, but this will prevent the FW idle opt
path from being executed. To handle this case we will
allow entry to idle opt from driver side even when a
PSR panel is connected under the following scenarios:
1. Only a single PSR panel is connected
2. PSR panel is not flipping
