[Intel-gfx] [PATCH 03/14] drm/i915/dsi: Always do panel power up delay on icl+

[Ville Syrjala]

From: Ville Syrjälä <ville.syrjala at linux.intel.com>

Windows doesn't try any tricks to optimize out the DSI panel power
delays. Let's follow suit since anything else is entirely untested
behaviour. Why would the VBT even specify a power on delay if we're
not supposed to use it?
