[PATCH 1/9][SRU][L][OEM-6.1] drm/i915: Introduce intel_panel_init_alloc()

[AceLan Kao]

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

BugLink: https://launchpad.net/bugs/2001599

Introduce a place where we can initialize connector->panel
after it's been allocated. We already have a intel_panel_init()
so had to get creative with the name and came up with
intel_panel_init_alloc().
