[v2,0/1] drm/i915/display: WA for Re-initialize dispcnlunitt1 xosc clock

Message

The dispcnlunit1_cp_xosc_clk should be de-asserted in display off
and only asserted in display on. But during observation it found
clk remains active in display OFF. As workaround, Display driver
shall execute set-reset sequence at the end of the Initialize
Sequence.
