drm/intel: Fix initialization if startup happens in interlaced mode [v2]
My EFI BIOS starts the graphics card up in my projector's preferred EDID
mode, 1080@60i. The Intel driver does not clear all the interlaced bits.
This patch introduces a new PIPECONF_INTERLACE_MASK define and uses it
to restore progressive mode.
