For higher refresh, to provide higher transfer time we need to disable
RSC solver in MDP. This can be configured through the panel timing node
devicetree property. This change adds the parsing of the devicetree
property.

Update the dump_mem pointer offset while storing the debugbus

As part of the change, register the DSI ctrl with sde_dbg from
ctrl_init directly, instead of debugfs_init to avoid code replication.

Currently on video mode panel, when the RFI bit clock
rate is set back to the default rate, the driver is not
detecting that a VRR operation is necessary due to
unchanged porches value.
This change is forcing a VRR update on video mode panel
whenever the RFI bit clock rate is changed.

Currently, on a video mode panel when a mode switch occurs after the RFI
bit clock rate has been changed, the driver fails to find the new mode
in the list of panel modes due to different porches value between
the adjusted mode and the default panel mode.
This change removes the front and back porch value check from mode
matching function when dynamic bit clock and maintain constant FPS
features are enabled.

Request for display in firmware only if no display enabled form
the UEFI.
In the targets supporting dual DSI display having both displays
DT nodes part of the connector list, if only one display is
enabled from the UEFI, then the driver requests for display
in firmware for the second display. Getting the display panel node
from firmware is time taking process, and it can take up to
ten seconds. This causes a delay in adding the component for the second
display, resulting in a delay in bind calls for components of the
msm drm driver.
