Tidy up defconfig files

There were some stale options set in the defconfigs, this replaces
them after running "make menuconfig". Most of this is benign since
the correct values should be forcibly set via "default" and "select".

- CrOS EC variables were stale

- Obsolete platforms removed
- Several devices (such as LPC ECs and Intel chipsets) were selected
  that are only present on x86 platforms, so unset those.

TEST=built and run on mario, alex, zgb, sumpy, lumpy, parrot,
stout, butterfly, spring, pit
