The related nodes are hdptxphy1_grf, hdptxphy1 and edp1. And the
aliases edp0 and edp1 are added to separate two independent eDP
devices.

drop aliases please

I will drop it and use the registers to separate edp0 and edp1 in the 
next version.

the hdptxphy nodes should be their own patch, also because most likely
Cristian's patch for hdmi1 [0] will be slightly faster.

Indeed, it is good to add edp1 node only.
