kconfig_lint: Check for IS_ENABLED used on symbols without CONFIG_
This looks at the coreboot codebase for the IS_ENABLED macro, and
gives an error if there is a symbol used without the CONFIG_ prefix.
This only works for symbols of type bool.
A future check will be added for all symbols, but that will take
a significant amount of time to run, because each symbol will need
to be searched for individually.
