Extend the "depends on" syntax to support conditional dependencies using "depends on X if Y". While functionally equivalent to "depends on X || (Y == n)", "depends on X if Y" is much more readable and makes the kconfig language uniform in supporting the "if <expr>" suffix. This also improves readability for "optional" dependencies, which are the subset of conditional dependencies where X is Y. Previously such optional dependencies had to be expressed as the counterintuitive "depends on X || !X", now this can be represented as "depends on X if X". The change is implemented by converting the "X if Y" syntax into the "X || (Y == n)" syntax during "depends on" token processing.
