ppc/pnv: Move timebase state into PnvCore
The timebase state machine is per per-core state and can be driven by any thread in the core. It is currently implemented as a hack where the state is in a CPU structure and only thread 0's state is accessed by the chiptod, which limits programming the timebase side of the state machine to thread 0 of a core. Move the state out into PnvCore and share it among all threads. Reviewed-by: Harsh Prateek Bora <harshpb@linux.ibm.com> Signed-off-by: Nicholas Piggin <npiggin@gmail.com>
