Subject: [PATCH] ARM: realview: hide unused 'pmu_device' object

The pmu_device is only accessed when CACHE_L2X0 is enabled,
and we get a warning otherwise:

mach-realview/realview_pbx.c:274:31: error: 'pmu_device' defined but not used [-Werror=unused-variable]

This adds another #ifdef for it.

Linus, I'm not sure how long you plan to keep the board file around,
so just ignore the patch if this is getting deleted anyway, otherwise
it would be nice if you could add the patch to your series.
