Update hreset HWP to always use scoms during HBRT

Previsouly there were checks in p9_sbe_hreset that made sure that
we only did getcfam ops on slave chips and did scoms to access the
registers on the master chips. This is correct for hostboot during
IPL time but during runtime we always want to use scom to access
these registers. This is safe because the fabric us up and we can
perform xscoms on both chips.
