Link Off Between Active Frames (LOBF) allows an eDP link to be turned Off and On durning long VBLANK durations without enabling any of the PSR/PSR2/PR modes of operation. Bspec: 71477 Note: Lobf need to be enabled adaptive sync fixed refresh mode where vmin = vmax = flipline, which will arise after cmmr feature enablement. Currently existing code refactored and make compute-config() and enabling function ready. Will add enabling sequence in a separate patch.
