When CONFIG_PM_OPP is not set, the definitions for these variables
are not available, so we should conditionally define them to
NULL.

I got this build error only now after pulling in the latest omap series, but
I cannot tell what caused it. It's also not clear to me if this is the correct
solution. Please ack or provide a better fix.
