[PATCH v2] ARM: vfp: Always save VFP state in vfp_pm_suspend

vfp_pm_suspend should save the VFP state any time there is
a last_VFP_context.  If it only saves when the VFP is enabled,
the state can get lost when, on a UP system:
   Thread 1 uses the VFP
   Context switch occurs to thread 2, VFP is disabled but the
      VFP context is not saved to allow lazy save and restore
   Thread 2 initiates suspend
   vfp_pm_suspend is called with the VFP disabled, but the
      context has not been saved.

Modify vfp_pm_suspend to save the VFP context whenever
last_VFP_context is set.
