Since we now call iwl_notification_wait_notify() from the
NAPI poll in soft-IRQ, we get a (valid) lockdep complaint
that we could get a deadlock by taking the spinlock from
sleeping context and then getting the soft-IRQ that also
tries to take it (in NAPI polling).
Fix this by disabling soft-IRQs for this lock.

Use SPDX tags instead of the long copyright notices. Also cleanup
some duplicate copyright notices and combine the years where possible.

The Free Software Foundation address is superfluous and causes
checkpatch to issue a warning when present. Remove all paragraphs
with FSF's address to prevent that.

The iwl_wait_notification() function removes the wait entry from the
list. To make it clearer that it's doing the same thing as
iwl_remove_notification(), call the latter instead of having duplicate
code.
