ppc/pseries: Reset VPA registration on CPU reset

Browse Source 
The ppc specific CPU state contains several variables which track the
VPA, SLB shadow and dispatch trace log.  These are structures shared
between OS and hypervisor that are used on the pseries machine to track
various per-CPU quantities.

The address of these structures needs to be registered by the guest on each
boot, however currently this registration is not cleared when we reset the
cpu.  This patch corrects this bug.
