Enable the HDMI output on the phyBOARD Pollux, using the HDMI encoder
present in the i.MX8MP SoC.
Please note that lcdif3 has not bee enabled. This is due the fact
that as of now either HDMI or LVDS may be enabled. If both are
enabled it won't worked. With this patch, however, HDMI can be
enabled by turning ldcif3 on and ldcif2 off.
