The eLCDIF controller on i.MX6UL/i.MX6ULL supports the alpha plane too.
Enable it on these SoCs.

While testing, I have noticed that the alpha plane works but
sometimes the framebuffer is shiftted to the right.
I tested with the following modetest command:
modetest -M mxsfb-drm -s 37@35:800x480 -P 33@35:800x480@AR24 -F smpte,plain
