Not all OPP entries fit into a single word. In particular NVIDIA Tegra OPP
tables use multi-word names. Allow OPP entry to have multi-worded name
separated by hyphen. This silences DT checker warnings about wrong naming
scheme.

Changelog:

v4: - Corrected pattern to retain matching of variants like 'opp1'.
      Was spotted by Rob Herring.

v3: - Viresh Kumar suggested that we shouldn't support postfix variant.
      I dropped variant with postfix naming scheme and multi-wording
      support of table names.

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