To facilitate use by SoC implementors working with bhnd-inheriting fdt/nexus
drivers:
* Splits bhnd_bus method implementations into generic bus implementations
(bhnd_bus_generic) and generic bhnd(4) driver implementations (bhnd_generic)
* Simplifies bhnd resource handling, allowing bhnd bus implementations to
support bhnd resource activation by implementing the standard BUS_*
resource APIs and BHND_BUS_ACTIVATE_RESOURCE().

This adds support for specifying the address space used by a bridge child;
this will either be the bridged SoC address space, or the host address space
required by children that map non SoC-address ranges from the PCI BAR.
This is necessary to support SROM/OTP child devices that live directly
beneath the bhndb device and require access to host resources, instead
of the standard behavior of delegating access to the bridged SoC address
space.

Summary:
PowerPC Book-E SMP is currently broken for unknown reasons. Pull in
Semihalf changes made c2012 for e500mc/e5500, which enables booting SMP.
This eliminates the shared software TLB1 table, replacing it with
tlb1_read_entry() function.
This does not yet support ePAPR SMP booting, and doesn't handle resetting CPUs
already released (ePAPR boot releases APs to a spin loop waiting on a specific
address). This will be addressed in the near future by using the MPIC to reset
the AP into our own alternate boot address.
This does include a change to the dpaa/dtsec(4) driver, to mark the portals as
CPU-private.
Test Plan:
Tested on Amiga X5000/20 (P5020). Boots, prints the following
messages:
Adding CPU 0, pir=0, awake=1
Waking up CPU 1 (dev=1)
Adding CPU 1, pir=20, awake=1

The ACPI and OFW PCI bus drivers as well as CardBus override this to
allocate the larger ivars to hold additional info beyond the stock PCI ivars.
This removes the need to pass the size to functions like pci_add_iov_child()
and pci_read_device() simplifying IOV and bus rescanning implementations.
As a result of this and earlier changes, the ACPI PCI bus driver no longer
needs its own device_attach and pci_create_iov_child methods but can use
the methods in the stock PCI bus driver instead.

as before. The common scheduling bits have moved from inline code in
each of the CAM periph drivers into a library that implements the
default scheduling.
In addition, a number of rate-limiting and I/O preference options can
be enabled by adding CAM_IOSCHED_NETFLIX to your config file. A number
of extra stats are also maintained. CAM_IOSCHED_NETFLIX isn't on by
default because it uses a separate BIO_READ and BIO_WRITE queue, so
doesn't honor BIO_ORDERED between these two types of operations. We
already didn't honor it for BIO_DELETE, and we don't depend on
BIO_ORDERED between reads and writes anywhere in the system (it is
currently used with BIO_FLUSH in ZFS to make sure some writes are
complete before others start and as a poor-man's soft dependency in
one place in UFS where we won't be issuing READs until after the
operation completes). However, out of an abundance of caution, it
isn't enabled by default.
Plus, this also brings in NCQ TRIM support for those SSDs that support
it. A black list is also provided for known rogues that use NCQ trim
as an excuse to corrupt the drive. It was difficult to separate out
into a separate commit.
