gator-driver: Fix building on Linux 3.12

In Linux 3.12 the local timer API was removed by commit 060fd304
(ARM: smp: Remove local timer API) so disable the check for this as it
stops compilation.

We need the check for kernels before 3.12 because otherwise we would
get incorrect timing information on A5/A9.
