ppc/pnv: Introduce user creatable pnv-phb4 devices

This patch introduces pnv-phb4 user creatable devices that are created
in a similar manner as pnv-phb3 devices, allowing the user to interact
with the PHBs directly instead of creating PCI Express Controllers that
will create a certain amount of PHBs per controller index.

We accomplish this by doing the following:

- add a pnv_phb4_get_stack() helper to retrieve which stack an user
created phb4 would occupy;

- when dealing with an user created pnv-phb4 (detected by checking if
phb->stack is NULL at the start of phb4_realize()), retrieve its stack
and initialize its properties as done in stk_realize();

- use 'defaults_enabled()' in stk_realize() to avoid creating and
initializing a 'stack->phb' qdev that might be overwritten by an user
created pnv-phb4 device. This process is wrapped into a new helper
called pnv_pec_stk_default_phb_realize().

ppc/pnv: turn 'phb' into a pointer in struct PnvPhb4PecStack

At this moment, stack->phb is the plain PnvPHB4 device itself instead of
a pointer to the device. This will present a problem when adding user
creatable devices because we can't deal with this struct and the
realize() callback from the user creatable device.

We can't get rid of this attribute, similar to what we did when enabling
pnv-phb3 user creatable devices, because pnv_phb4_update_regions() needs
to access stack->phb to do its job. This function is called twice in
pnv_pec_stk_update_map(), which is one of the nested xscom write
callbacks (via pnv_pec_stk_nest_xscom_write()). In fact,
pnv_pec_stk_update_map() code comment is explicit about how the order of
the unmap/map operations relates with the PHB subregions.

All of this indicates that this code is tied together in a way that we
either go on a crusade, featuring lots of refactories and redesign and
considerable pain, to decouple stack and phb mapping, or we allow stack
update_map operations to access the associated PHB as it is today even
after introducing pnv-phb4 user devices.

This patch chooses the latter. Instead of getting rid of stack->phb,
turn it into a PHB pointer. This will allow us to assign an user created
PHB to an existing stack later. In this process,
pnv_pec_stk_instance_init() is removed because stack->phb is being
initialized in stk_realize() instead.

ppc/pnv: move PHB4 XSCOM init to phb4_realize()

ppc/pnv: move PHB4 XSCOM init to phb4_realize()

The 'stack->phb_regs_mr' PHB4 passthrough XSCOM initialization relies on
'stack->phb' being not NULL. Moving 'stack->phb_regs_mr' region_init()
and add_subregion() to phb4_realize() time is a natural thing to do
since it's strictly PHB related.

The remaining XSCOM initialization is also related to 'stack->phb' but
in a different manner. For instance, 'stack->nest_regs_mr'
MemoryRegionOps, 'pnv_pec_stk_nest_xscom_ops', uses
pnv_pec_stk_nest_xscom_write() as a write callback. When trying to write
the PEC_NEST_STK_BAR_EN reg, pnv_pec_stk_update_map() is called. Inside
this function, pnv_phb4_update_regions() is called twice. This function
uses 'stack->phb' to manipulate memory regions of the phb.

This is not a problem now but, when enabling user creatable phb4s, a
stack that doesn't have an associated phb (i.e. stack->phb = NULL) it
will cause a SIGINT during boot in pnv_phb4_update_regions().

All this can be avoided if all XSCOM realize is moved to phb4_realize(),
when we have certainty about the existence of 'stack->phb'. A lot of
code was moved from pnv_phb4_pec.c to pnv_phb4.c due to static constant
and variables being used but the cleaner logic is worth the trouble.

Relying on stack->phb to write the xscom DT of the PEC is something that

Hopefully, this can be done by using pnv_phb4_pec_get_phb_id(), which is
already used by pnv_pec_realize() to set the phb-id of the stack. Use
the same idea in pnv_pec_dt_xscom() to write ibm,phb-index without the
need to accessing stack->phb, since stack->phb is not granted to be !=
NULL when user creatable phbs are introduced.

Not exactly elegant, I'm afraid.

The "when != lbl:" is necessary to avoid transforming

even though other paths to label out still need the error_propagate().
For an actual example, see sclp_realize().

Without the "when strict", Coccinelle transforms vfio_msix_setup(),
incorrectly. I don't know what exactly "when strict" does, only that
it helps here.

The match of return is narrower than what I want, but I can't figure
out how to express "return where the operand doesn't use @err". For
an example where it's too narrow, see vfio_intx_enable().
