drm/i915: fix initial timestamps for PP sequencing logic
The initial jiffies value can be non-0, so set the inital panel power
sequencer timestamps accordingly. This didn't cause a problem on 64 bit
machines but on 32 bit jiffies is initially -300*HZ, so if the panel
power is initally off in the call from edp_panel_vdd_on()->
wait_panel_power_cycle() we'd wait up to ~300 sec more than needed.
