[RFC V1 4/6] powerpc: Add flag in paca for register restore state

[Mukesh Kumar Chaurasiya]

In case of signal being processed we want to restore the GPRS. To save the state
of whether we need to restore the registers or not a flag is introduced so that
we can save the state for that cpu in case we want to save the register state.
