drm/i915: Try harder during dp pattern 1 link training Instead of going through the sequence just once, run through the whole set up to 5 times to see if something can work. This isn't part of the DP spec, but the BIOS seems to do it, and given that link training failure is so bad, it seems reasonable to follow suit.
