nb/intel/hsw,soc/intel/{bdw,skl,apl},mb/*: unify dt panel settings
There are multiple different devicetree setting formats for graphics
panel settings present in coreboot. Replace the ones for the platforms
that already have (mostly) unified gma/graphics setup code by a unified
struct in the gma driver. Hook it up in HSW, BDW, SKL, and APL and adapt
the devicetrees accordingly.
Always ensure that values don't overflow by applying appropriate masks.
The remaining platforms implementing panel settings (GM45, i945, ILK and
SNB) can be migrated later after unifying their gma/graphics setup code.
