arch: arc: Kconfig: Remove redundant 'default n' properties

Browse source 
Bool symbols implicitly default to 'n'.

A 'default n' can make sense e.g. in a Kconfig.defconfig file, if you
want to override a 'default y' on the base definition of the symbol. It
isn't used like that on any of these symbols though.

Also fix the 'default' on XIP. Due to Zephyr's prefer-later-defaults
behavior, it was always set to 'y' (when the dependencies were
satisfied).
