ec/google/chromeec: Enclose Kconfig in 'if/endif' block

Instead of having things depend on EC_GOOGLE_CHROMEEC, just put an if/
endif block around the configs.

The 'source' line stays outside of the if block because the source
always happens, even if it's inside an if/endif block. Each of the
sub-Kconfigs here already has an if/endif block surrounding the
contents.
