Rediscover location of HDAT data to handle IO CM operations
PHYP modifies the location of the HDAT memory during a IO CM
operation. During a mpipl, during dump collection, HB will
cache the location of the SPIRA. This cache will be pointing
to the B side. Later in the boot the FSP repopulates the SPIRA
using the A side. HB needs to use the A side pointers instead.
