sync_state driver disables any resources that

Move MDSS resource votes to probe so that any resources
that are needed for continuous splash are intact until
the bind of all the components is complete.

Msm_drv device node has dependency on sde_rsc device
node for power resource enable if sde_rsc device
device is enabled. This change moves the msm_drv device
to probe defer state during component addition if
sde_rsc device is not probed yet. It also removes
the master_drm device node access from sde_rsc device.

Updating qos remap updates requires reading registers to update values,
this adds additional CPU processing when in reality this update

This change introduces pre-downscaling values to the path where
these values are not provided by userspace. Currently, pre-downscaling
is only allowed by a factor of 2.2 in the x direction. With this
change pre-downscaling will support >2.2 up to 4 in the x direction.

The color-processing partial update check wrongly
assumes that all pipes in a CRTC have a DSPP attached.
This inhibits the use of any LMs without a valid DSPP.
Fix the issue by removing this invalid check since whenever
a DSPP feature is required, the HW resource availability is
already confirmed during the color-processing property validation.

Add a QoS vote on CPU receiving display interrupt. QoS vote
will prevent that CPU from going into low power mode avoiding
possible interrupt latency. Using irq notifier, display will
receive notification when display IRQ has switched CPUs and
will adjust the vote accordingly. The vote is also removed and
requested whenever display IRQ is enabled or disabled.

before host_init which can lead to noc error while accessing dp_aux
registers. To prevent that set abort flag to abort lib auth work and
set interrupts before host_deinit.

Ensure host_init is executed when the DP display driver is resuming
from a video session teardown. The host_deinit is executed when DP
video session teardown is initiated by the userspace while DP cable
is connected. If the DP display is disconnected from dongle while
the video session is in teardown, the host_init is not executed
when the session is restored. All subsequent display connections
will fail because the core clocks are not on and aux abort is not
reset.
This change will ensure host_init is executed whenever the
host_deinit is executed during DP video session teardown by userspace.

The hpd notification is skipped in connect_work if there is an
attention_work pending. So, the notification has to be sent in
attention_work.
Some dongles issue multiple attention events with LINK_STATUS_UPDATED
while the connect_work is in progress. So, once the link training
is successfully completed the LINK_STATUS_UPDATED attention event is
considered handled and the attention_work scheduled to execute after
the connect_work will return early without handling the
hpd_notification cases.
This change will ensure the hpd_notification is sent from
attention_work in such cases.
