[PATCH 00/17] remove PnvPhb4PecStack from Powernv9

[Daniel Henrique Barboza]

Hi,

After all the done enabling pnv-phb4 user devices, it became clear that
the stack object is just a container of the PHB and its resources than
something that needs to be maintained by its own. Removing the
PnvPhb4PecStack object promotes a simpler code where we're dealing only
with PECs and PHB4s.

One thing that isn't handled in this series is the nested regs names.
There are 30+ nested per-stack registers with names such as
'PEC_NEST_STK*' or 'PEC_PCI_STK*' that are left as is. Renaming them to
remove the 'STK' reference can be done in a follow up when we're
satisfied with what it is presented here.

No functional change is intended with this series. The series is based
on top of current master (at f8d75e10d3),
