mb/google/zork/morphius: Drop touchscreen detection 

Morphius boards using pre-v3.6 schematics don't have a dedicated GPIO
for touchscreen power/enable, and so fail with runtime detection
enabled. Since it only has one touchscreen option, and no SKUs lack a
touchscreen, we can safely assume it is present in all cases.

TEST=build/boot morphius w/4k screen, verify touchscreen enabled in
cbmem and functional in Linux and Windows.
