This patchset enables freesync video mode usecase where the userspace
can request a freesync compatible video mode such that switching to this
mode does not trigger blanking.

This feature is guarded by a module parameter which is disabled by
default. Enabling this paramters adds additional modes to the driver
modelist, and also enables the optimization to skip modeset when using
one of these modes.
