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.
