video: tegra: dc: tag vrr modes using vmode

HDMI VRR is supported only for some resolutions, and the kernel
driver is aware of these restrictions. For VRR monitors, the kernel
driver now duplicates and tags all compatible modes with the
FB_VMODE_VRR flag in the duplicate mode's fb_videomode vmode field.

The same behavior has been added to DSI as well for consistency.

The compatible modes are duplicated before being tagged so as to
not interfere with userspace configurations that do not support
the FB_VMODE_VRR flag.
