drm/i915/alpm: Do not use fast_wake_lines for aux less wake time

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
