From: Daniel Henrique Barboza <danielhb413@gmail.com>

Move the current pnv_pec_stk_default_phb_realize() call to
pec_realize(), renaming the function to pnv_pec_default_phb_realize(),
and set the PHB attributes using the PEC object directly.

This will be important to allow for PECs devices to handle PHB4s
directly later on.
