kconfig_lint: Exclude some Kconfig symbols from unused symbol checks
The configuration that coreboot uses for setting selected symbols typically involves a structure like this: config BLEH_SPECIFIC_OPTIONS def_bool y select SYMBOL This leads to an an extra kconfig symbol BLEH_SPECIFIC_OPTIONS that is never referenced by anything else, generating a warning. Since this is currently the construct that coreboot uses, filter it out of the warnings for now.
