Commit 13ea6db2cf24 ("drm/i915/edp: Ignore short pulse when panel
powered off") completely broke short pulse handling for eDP as it is
usually generated by sink when it is displaying image and there is
some error or status that source needs to handle.
When power panel is enabled, this state is enough to power aux
transactions and VDD override is disabled, so intel_pps_have_power()
is always returning false causing short pulses to be ignored.
So here better naming this function that intends to check if aux
lines are powered to avoid the endless cycle mentioned in the commit
being fixed and fixing the check for what it is intended.
v2:
- renamed to intel_pps_have_panel_power_or_vdd()
- fixed indentation
