Add the required resets and clocks used by the display engine TCON for
LCD output. This is required for LCD output for the DE33 which is
currently pending acceptance into mainline.

do exist on every H616 die, the respective LCD controllers are not
exposed on the H616 package, but only on the T507 and H700 version.
