drm/i915: edp resume/On time optimization.
Make resume/on codepath not to wait for panel_power_cycle_delay(t11_t12)
if this time is already spent in suspend/poweron time.
v2: Use CLOCK_BOOTTIME and remove jiffies for panel power cycle
delay calculation(Ville).
v3: Addressed below comments
1. Tracking time from where last powercycle is initiated.
2. Used ktime_get_bootime() wrapper for boottime clock.
3. Used ktime_ms_delta() to get time difference.
v4: Updated v3 change log in detail.
v5: Removed static from panel_power_on_time(Stéphane).
