[PATCH 11/17] pnv_phb4_pec.c: use pnv_pec_get_phb_id() in pnv_pec_dt_xscom() |

Relying on stack->phb to write the xscom DT of the PEC is something that
we won't be able to do with user creatable pnv-phb4 devices.
Hopefully, this can be done by using pnv_pec_get_phb_id(), which is
already used by pnv_pec_realize() to set the phb-id of the stack. Use
the same idea in pnv_pec_dt_xscom() to write ibm,phb-index without the
need to accessing stack->phb, since stack->phb is not granted to be !=
NULL when user creatable phbs are introduced.
