Like commit 512660cd1f ("drm/xe/rtp: Expand max rules/actions per
entry") did, expand the maximum number of actions/rules. That commit was
too conservative, just incrementing 2. Other than the ugliness of these
macros and additional preprocessor steps when they are used, there are
no downsides on increasing the maximum: the tables in which they are
used use a sentinel to mark the last element.
With rtp processing now supporting OR rules, it's possible to migrate
the extension made for OOB WAs that "entries with name are OR'ed in
previous entry". For that the maximum number of rules needs to be
increased.
Just double it. Hopefully 12 is sufficient for longer than 6 was.
