[PATCH for-7.2 v4 09/11] ppc/pnv: change pnv_phb4_get_pec() to also retrieve chip10->pecs

[Daniel Henrique Barboza]

The function assumes that we're always dealing with a PNV9_CHIP()
object. This is not the case when the pnv-phb device belongs to a
powernv10 machine.

Change pnv_phb4_get_pec() to be able to work with PNV10_CHIP() if
necessary.
