[PATCH v4 0/5] user creatable pnv-phb4 devices

[Daniel Henrique Barboza]

Hi,

This new version contains the remaining v3 patches that weren't accepted
yet, which is the case of patches 10, 2 and 3.

There are fewer patches this time due to 2 design changes made: move the
phb property setup to stk_realize() and all XSCOM initialization to
phb4_realize().

As a note/TODO, at the end of this work it became clear that it would be
interesting to rethink what we expect about the PnvPhb4Stack object
in the overall design. The object ended up with no init() and its realize
is used as a glorified setup for its phb, being a no-op if the user runs
with -nodefaults. There might be an opportunity for further cleanups and
simplifications.

changes from v3:
- patches 2, 3, and 10 from v3: accepted
- patch 1:
  * do not create a function to set the properties
  * set all properties in stk_realize()
  * remove the 'phb-id' link during this process instead of using a separated
patch
- patch 2:
  * move all XSCOM init to phb4_realize()
- patch 4:
  * review changes proposed by Cedric in v3
- patch 5 (new):
  * a trivial cleanup following patch 2
