28586889c2 Convert PCIe Hot Plug to using pci_request_feature
Convert PCIe hot plug support over to asking the firmware, if any, for
permission to use the HotPlug hardware. Implement pci_request_feature
for ACPI. All other host pci connections to allowing all valid feature
requests.

a1e1814d76 As <machine/pmap.h> is included from <vm/pmap.h>, there is no need to
include it explicitly when <vm/pmap.h> is already included.

2dd1bdf183 Convert rman to use rman_res_t instead of u_long
Summary:
Migrate to using the semi-opaque type rman_res_t to specify rman resources.  For
now, this is still compatible with u_long.

This is step one in migrating rman to use uintmax_t for resources instead of
u_long.

Going forward, this could feasibly be used to specify architecture-specific
definitions of resource ranges, rather than baking a specific integer type into
the API.

This change has been broken out to facilitate MFC'ing drivers back to 10 without
breaking ABI.

18c72666ce Add domain support to PCI bus allocation
When the system has more than a single PCI domain, the bus numbers
are not unique, thus they cannot be used for "pci" device numbering.
Change bus numbers to -1 (i.e. to-be-determined automatically)
wherever the code did not care about domains.

c37904e8ba Reshuffle all of the DDR flush operations into a single switch/mux,
and start teaching subsystems about it.

The Atheros MIPS platforms don't guarantee any kind of FIFO consistency
with interrupts in hardware.  So software needs to do a flush when it
receives an interrupt and before it calls the interrupt handler.

There are new ones for the QCA934x and QCA955x, so do a few things:

* Get rid of the individual ones (for ethernet and IP2);
* Create a mux and enum listing all the variations on DDR flushes;
* replace the uses of IP2 with the relevant one (which will typically
  be "PCI" here);
* call the USB DDR flush before calling the real USB interrupt handlers;
* call the ethernet one upon receiving an interrupt that's for us,
  rather than never calling it during operation.

Tested:

* QCA9558 (TP-Link archer c7 v2)
* AR9331 (Carambola 2)

TODO:

* PCI, USB, ethernet, etc need to do a double-check to see if the
  interrupt was truely for them before doing the DDR.  For now I
  prefer "correct" over "fast".

b2c9e1e324 Add initial support for the QCA955x PCIe host controller.
The QCA955x looks a lot like the AR724x PCIe controller, except it
supports two root complexes.  Unfortunately I only have one, so
although this code has started down the path of supporting more than
one, it's definitely not yet ready.

Tested:

* AP135 board (QCA9558 SoC), with the 11ac NIC swapped for an AR9380
  PCIe NIC.

Notes:

* Yes, this driver isn't very pretty.  I decided to commit what I have
  versus holding onto something that isn't yet finished.  It is enough
  to bring up the above NIC and interrupt routing works, so it's a good
  start.

* However, yes, the DDR flush routine hooks need to be fixed up.
  I don't think I'm firing the right one at the moment.
