Do hardware timebase sync. Firstly, stop all timebases, and transfer
the timebase value of the boot core to the other core. Finally,
start all timebases.

Only apply to dual-core chips, such as MPC8572, P2020, etc.

Changes for v6:
 * added 85xx_TB_SYNC
 * added isync() after set_tb()
 * removed extra entries from mpc85xx_smp_guts_ids

What's that CONFIG option for ?

Cheers,
