Add sideband simulator aux bridge to re-direct sideband message
from aux channel to internal emulation software stack. When this
bridge is connected to DP device, simulator will read ports configuration
from device tree and fake all sideband messages.

DP driver maintains the number of allocated DSCs per stream for managing
the availability of DSC blocks for each stream. In the current driver,
if there are errors in the disable path, it is possible for the refcount
to go negative thereby affecting the availability of DSC blocks in
subsequent enables.
This change fixes the refcount logic by making sure the DSC count in the
context correctly reflects the usage.

drm_mode_vrefresh API from now on.
This change removes dependency on drm_display_mode vrefresh
and replaces it with drm_mode_vrefresh API in SDE, DSI and
DP driver. In addition, it also modifies drm_display_mode clock
to align with upstream approach where an uncompressed mode clock
is required to match drm_mode_vrefresh API.
