[PATCH v3 04/10] pnv_phb4_pec.c: remove stack 'phb-id' alias

[Daniel Henrique Barboza <danielhb413@gmail.com>]

This alias is a indirect way of setting stack->phb->index. Since we have
access to a valid stack->phb (for default_enabled() at least - next
patch will deal with it accordingly) we can directly set the phb 'index'
attribute.

Let's also take the opportunity to explain why we're having to deal with
stack->phb attributes during pec_realize().
