Subject: [PATCH v2] dt-bindings: opp: Allow opp-table postfix and multi-worded node names

Not all OPP table names and OPP entries consist of a single word. Not all
OPP tables start with opp-table- prefix. In particular NVIDIA Tegra OPP
tables use multi-word names and have -opp-table postfix. Allow OPP node
and OPP entry names to have multi-worded names. Allow to use the postfix
variant. This corrects DT checker warnings about the wrong naming scheme.

Changelog:

v2: - In addition to a multi-wording support, support of the postfix
      *-opp-table naming scheme is added to the updated pattern.
