Add changes to commit and decrement only those
hardware resources which are required for the modeset.
Timeline of Commit C1 with CWB modeset:
---> Atomic_check
Primary encoder has allocated required HW resources.
CWB encoder has allocated required HW resources.
---> Atomic_commit
On primary encoder, connector is seamless hence
there is no virt_modeset call.
On CWB encoder, there is virt_mode_set call
and during commit HW blocks there is unconditional
decrement for all the HW blocks with rsvp_nxt.
This change ensures hardware blocks are available during
dp display mode validations.

In atomic test phase DSC Hw block should be allowed to be reserved
without checking the mode information. Mode information is not
available before bridge enable is called and this results into dsc
not programmed very first mode set.

This change introduces new ctl path api read_active_status to check
if a particular hw block is active or not in the current control path.
This is specially required in continuous splash use case when bootloader
has programmed certain blocks and the kernel driver tries to find
out the same configuration. This is used to ascertain which DSC block
is active in continuous splash case since DSC blocks are not tied to
mixer blocks.

Certain DSC hw blocks only support 444 mode, while others
support both 444 and 422 modes. This change adds support in
resource manager to check the hw resource requirement with
the capability of the block and then reserve the correct
hw resource.

RM blocks an lm path with dspp from being allocated if a dspp is
not required by topology. This can restrict using all lms to full
availability. LM preference already ensures dspp
assignment is completed to required built in displays.
This change removes blocking conditions.

In dual display cases when secondary display is resumed first,
primary CTL and LM is selected for secondary path which leads to

LM to secondary connector.

RM does not currently check dsc pairs while reserving, but
this could lead to an incompatible pair being allocated. The
hw restrictions are populated from dtsi and checked during

Primary and secondary displays should have first priority
when reserving lms. Static reservation can potentially block
higher resolutions for the required displays. This patch gets
the layer mixer requirement for primary or secondary display
if available. It reserves those layer mixers dynamically
for the respective display when connector is registered.

On the first commit, cont splash flag is still enabled on
encoder, but connector is not yet attached. When a check-only
rm reservation is made, it does not get released due to
cont-splash check. If cont-splash is enabled, rm should
not check for connector, but directly release rsvp_nxt.
