[Intel-gfx] [RESEND PATCH] drm/dp: Increase link status size

[Thierry Reding]

From: Thierry Reding <treding at nvidia.com>

The current link status contains bytes 0x202 through 0x207, but we also
want to make sure to include the DP_ADJUST_REQUEST_POST_CURSOR2 (0x20c)
so that the post-cursor adjustment can be queried during link training.
