This check had very few false positives which were all easily resolved,
and it's unlikely that further false positives will become problematic
in the future. On the other hand, it does detect a very severe bug (when
you think you're using a Kconfig but you aren't due to a typo), so since
warnings are currently not very visible, let's turn this into an error
because the pros clearly outweigh the cons for that.

This patch changes a few more Kconfig linter warnings to errors that
currently do not show up in the tree and that seem unlikely to become
false positive in the future. One instance of duplicated code that
essentially checks for the same thing was consolidated.
It also adds a new test for references to boolean Kconfig options that
do not use the CONFIG() wrapper macro. It's a little flaky (e.g. hard to
handle multi-line comments), but it should be helpful the majority of
the time as a warning in a Jenkins comment.

This is a great check, but unfortunately it's currently not effective
because most uses of IS_ENABLED() do not have whitespace in front of
them (they're mostly used as part of an if (IS_ENABLED(...)) condition).
This patch makes the linter a little more generous in what it considers
in scope to avoid these false negatives in the future.

Because the help block uses significant whitespace to determine whether
or not text is inside the help block, a mixture of spaces and tabs
confuses the parser.
If there's an unrecognized line, and the previous line was inside a help
block, it's likely that this line is too.
Additionally, this was found with a line that started ' configuration',
and threw a perl warning about an uninitialized value because the parser
thought this was the start of a new config line, but couldn't find the
symbol. Now we make sure that config statements have whitespace after
the 'config' statement.

This is a tool to help identify issues in coreboot's Kconfig structure
and in how the Kconfig symbols are used in the coreboot codebase.
It identifies a number of issues:
- #ifdef used on Kconfig symbol of type bool, hex, or int. These are
always defined.
- #define CONFIG_ in the coreboot code - these should be reserved
for Kconfig symbols.
- Redefinition of Kconfig symbols in the code.
- Use of IS_ENABLED() on non-bool kconfig symbols.
- Use of IS_ENABLED() on values that are not kconfig symbols.
- Attempts to find default values that will not set anything
because of earlier default settings. This needs to be expanded
significantly.
- Kconfig expressions using symbols which are not defined.
- Kconfig symbols that are defined but not used anywhere in the
Kconfig structure or coreboot code.
- Kconfig keywords used incorrectly.
- Whitespace issues
- Kconfig 'source' keyword issues
-- sourcing non-existant directories
-- sourcing Kconfig files multiple times
-- sourcing non-existent files
-- Kconfig files in the codebase that are never sourced
Additionally, it can be used to help debug the Kconfig tree
by putting all the files together into a single file with
their source locations listed.
