mb/google/guybrush: Switch eSPI to 16 MHz
It looks like we are having SI issues on eSPI at 33 MHz. Switching to 16
MHz makes everything a lot more stable.
BUG=b:183524609
TEST=Boot to OS and run `ectool version` 1000 times and see no problems.
Before with 33 MHz there was an error every few cycles.
declare -i i=0; while ectool version; do i+=1; echo "$i"; sleep .11; done; echo "Finished: $i"
