drm/xe/rtp: Allow to OR rules

Browse source

Some workarounds started to depend on different set of conditions where
the action should be applied if any of them match. See e.g.
commit 24d0d98af1 ("drm/xe/xe2lpm: Fixup Wa_14020756599"). Add
XE_RTP_MATCH_OR that allows to implement a logical OR for the rules.
Normal precedence applies:

	r1, r2, OR, r3

means

	(r1 AND r2) OR r3

The check is shortcut as soon as a set of conditions match.

v2: Do not match on empty number of rules-other-than-OR evaluated
