doc: avoid non-standard value for Kconfig predefines
doc: avoid non-standard value for Kconfig predefines

When building with Kconfig a symbol CONFIG_FOO is either undefined, or
defined to the integer literal 1.  There are styles and use cases
where this is important, e.g. using "#if (CONFIG_FOO - 0)" which would
not work with a macro expanding to the identifier y.  Use the standard
default definition instead of a special non-default one.

Also consistently use space rather than tab indentation within the
multi-line setting, and alphabetize the CONFIG_ predefines.
