mb/google/kukui: Initialize display

Many devices in Kukui family will be using MIPI panels, which needs
hard-coded EDID and initialization commands. And because each device may
have its own layout and ID, there should be very few devices sharing
same panel configuration. As a result, we want to put panel data (EDID
and init commands) into board-specific modules, provided by
`get_panel_description` function.

The panel numeric ID is identified by ADC 2, and is currently available
as higher 4 bits of sku_id(). After ID is retrieved, the
get_panel_description should return a reference to the EDID and table of
init commands. The default implementation is to simply return NULL, and
the data for real devices should be provided by panel_*.c in further commits.
