kconfig: syntax cleanup - drop support for "depends/requires/def_boolean"

Remove the following redundant and never or rarely used kconfig syntax:

- "def_boolean" (same as "def_bool")
- "requires" (same as "depends on")
- "depends" (same as "depends on")

This patch contains the code changes and Kconfig updates.
The shipped files are in next patch to let actual codechange stand out.
