ARM: 7476/1: vfp: only clear vfp state for current cpu in vfp_pm_suspend

Browse source 
vfp_pm_suspend runs on each cpu, only clear the hardware state
pointer for the current cpu.  Prevents a possible crash if one
cpu clears the hw state pointer when another cpu has already
checked if it is valid.
