If host bridge does not have mmio64 above 4G, We don't need to
treat device non-pref mmio64 as as pref mmio64.

For device resource PREF bit setting under bridge 64-bit pref resource,
we need to make sure only set PREF for 64bit resource, so set
IORESOUCE_MEM_64 for 64bit resource during of device resource flags
parsing.

On hotplug path, we can not touch sibling bridges that is out
side of the slot.
That could happen when BIOS does not assign some bridge BARs and
later can not assign resource to them in first try.
Check if fail dev is the parent bridge, then just use subordinate
bus instead use parent bus.

Current code will always add 2M for hotplug bridge mmio even
there is child device under it.
For example:
40:03.0 --- 43:00.0 --- 44:02.0 -+- 45:00.0
\- 45:00.1
44:02.0 will need 1M as must for 45:00.0 and 45:00.1

Not yet, it's behind
After we update size and alignment for must+optional resource, we
reorder them with new alignment, but this is only for STARTALIGN.
For SIZEALIGN type resource, after add back add_size, the alignment
get changed, so need to do the sorting like STARTALIGN type resources.
Also we need to reorder

We need to reserve them before pci_bus_add().
During driver loading kernel will check if those reource get reserved.
On remove/rescan path, we will leave those fixed resource
not reserved, as we don't call pcibios_resource_survery() before
pci_assign_unassigned_bus_resources(), and that is
Find all suitable empty slots and pick one just fit, so we could save
the big slot for needed ones later when we have several pcie switches
and some bridges get assigned bios and we need to assign others in kernel.

We check the realloc list, as list must be empty after allocation.
Separate the realloc list checking to another function.
Add checking that is missed in acpiphp driver.

We try to assign must+optional at first, and we only accept the result if
all resources get allocated. Otherwise will release assigned in the list,
and try to assign must and expand to optional.
We have to do that to make sure any must has priority than any optional
addon.
When that happens, we

Skip allocated resource in the list, as pci_assign_resource()
only can handle not assigned resource. And we could have
assigned resource already in the list before alt_size trying.

If the bridge does not support hotplug or no child with sriov support
we could get out early and don't try must+optional allocation.
Also in the loop that update res with optional add info, skip resource
that add_size is 0.

This patch implements the SCIF mmap/munmap interface. A similar
capability is provided to kernel clients via the
scif_get_pages()/scif_put_pages() APIs. The SCIF mmap interface
queries to check if a window is valid and then remaps the local
virtual address to the remote
So could reallocate pref mmio64 above 4G later.
