mb/[google/intel]/*: Specify Chrome EC bus - LPC or ESPI

Previously all boards using eSPI for the Chrome EC just called it
LPC as the code for the chrome EC is the same between the two
busses.

I'm adding a new Kconfig symbol to specify eSPI, so switch the
boards that actually use eSPI to that symbol and add the LPC
symbol to all the others.

The EC_GOOGLE_CHROMEEC_LPC symbol will no longer default
to enabled for x86 platforms, so one symbol or the other needs to be
specified for each platform.

BUG=b:140055300
TEST=Build tested only.
