src: Change BOOL CONFIG_ to CONFIG() in comments & strings

The Kconfig lint tool checks for cases of the code using BOOL type
Kconfig options directly instead of with CONFIG() and will print out
warnings about it.  It gets confused by these references in comments
and strings.  To fix it so that it can find the real issues, just
update these as we would with real issues.
