Legacy xtensa had a rather complicated implementation of en/disabling
interrupts, owing to the "software priority" feature (which plays
games with INTENABLE and INTLEVEL to allow for interrupts to interrupt
each other outside their normal priorities). But that's not a Zephyr
feature, it's enabled by a XT_USE_SWPRI value that comes from platform
headers and isn't enabled on any of our boards. Dead code, basically.
Replace with the obvious implementation when asm2 is in use.

This was a dead API. Nothing ever used it, it wasn't exposed in any
API headers. It never appeared in documentation. It's not
particularly clear why a Zephy app would want to hook
architecture-specific exceptions instead of simply using the portable
error framework anyway. And it's not supported by asm2. Delete.

Master branch changed requirements for license headers while this
branch has been in development.
