ARM: highbank: avoid L2 cache smc calls when PL310 is not present
commit
a56a5cf1f2ec895599eace0ac6eba1e4a489e4bf upstream.
While Midway firmware handles L2 smc calls as nops, the custom smc calls
present a problem when running virtualized Midway guest. They aren't
needed so just avoid calling them.
In the process, cleanup the L2X0 ifdefs and use IS_ENABLED instead.
