[POWERPC] iSeries: Use alternate paca structure for booting

The iSeries HV only needs the first two fields of the paca statically
initialised, so create an alternate paca that contains only those and
switch to our real paca immediately after boot.

This is in order to make the 1024 cpu patches easier since they will no
longer have to statically initialise the pacas for iSeries.
