[Angel Pons (Code Review)]

Hello build bot (Jenkins), Nico Huber, Patrick Georgi, Martin Roth, Matt DeVillier, Arthur Heymans,

I'd like you to reexamine a change. Please visit

mb/purism/librem_cnl: Add libgfxinit support

Only the DisplayPort output is working as of now. The HDMI 2.0 output is
provided by a Parade DP175 LSPCON, which is internally connected to DP2.
LSPCON setup in libgfxinit is missing as of now, but will be added soon.
