We want to have own variables for fast wake lines and aux less wake
time. It might be needed to choose if we can enable Panel Replay Selective
Update or PSR2.
Also currently aux less wake time is overwritten by calculated fast wake
time.
v2:use aux less wake time in intel_alpm_lobf_compute_config

Set the Link Off Between Frames Enable bit in ALPM_CTL register.
Note: Lobf need to be enabled adaptive sync fixed refresh mode
where vmin = vmax = flipline, which will arise after cmmr feature
enablement. Will add enabling sequence in a separate patch.
v1: Initial version.
v2: Condition check modified in alpm_configure(). [Jouni]

Link Off Between Active Frames, is a new feature for eDP
that allows the panel to go to lower power state after
transmission of data. This is a feature on top of ALPM, AS SDP.
Add compute config during atomic-check phase.
v1: RFC version.
v2: Add separate flag for auxless-alpm. [Jani]
v3:
- intel_dp->lobf_supported replaced with crtc_state->has_lobf. [Jouni]
- Add DISPLAY_VER() check. [Jouni]
- Modify function name of get_aux_less_status. [Jani]
v4: Add enum alpm_mode to hold the aux-wake/less capability.
v5: Add alpm_dpcd to intel_dp and use aux_wake_supported()/
aux_less_wake_supported() instead of enum alpm_mode. [Jouni]
