Add static cti_assoc_ops to coresight core driver. Let cti
driver register the add_assoc and remove_assoc call back.
Avoid coresight core driver to depend on cti driver.

Checking for ifdef CONFIG_x fails if CONFIG_x=m. Use IS_ENABLED
that is true for both built-ins and modules, instead. Required

Good day,
This is the second part we were hoping for, i.e CoreSight modularisation,
and a fix for a copy/paste error in the context save/restore process.
Please consider for the next merge window.
Applies on top of your "char-misc-next" branch.
Thanks,
Mathieu

Hi Alexander,
Things have been quite busy over the last 3 weeks, preventing me from
giving your work the attention it deserves. It is on my radar and will get to
it in the next two weeks.
Thanks,
Mathieu
