Ampere Altra in a dual socket configuration has 12 ITSes for the
12 PCIe root complexes. The NIRQ interrupts are statically split
between each child of the gic bus, so here we increase that
value. 16k is enough for
(#cpus * #its * max_pcie_bifurcation) LPIs + (#SPIs and #PPIs)

As the pl061 driver can be an interrupt controller attach it earlier in the
boot so other drivers can use it.
Use a new GPIO xref to not conflict with the existing root interrupt
controller.

framework has significantly changed the driver has moved to a new file.
While it shares some code with the existing driver this has been modified
to work better with the intrng framework.
This has been tested on the ThunderX servers in the netperf cluster and has
been used to boot them for other testing, including DTrace and hwpmc.
With this we can use intrng on all supported arm64 platforms I was able to
test on. It is expected we will move to intrng soon, and disable the old
arm64 interrupt framework.

updated, and until further testing can be done, this is disabled for now.
It is expected arm64 will switch to this interface, and the old interface
will be removed before 11.0 is released.

It can be used to bind specific interrupt to a particular CPU.
Requires PIC support for interrupts binding.

This is only the minimum set of files needed to boot in qemu. As such it is
missing a few things.
The bus_dma code is currently only stub functions with a full implementation
from the development tree to follow.
The gic driver has been copied as the interrupt framework is different. It
is expected the two drivers will be merged by the arm intrng project,
however this will need to be imported into the tree and support for arm64
would need to be added.
This includes code developed by myself, SemiHalf, Ed Maste, and Robin
Randhawa from ARM. This has been funded by the FreeBSD Foundation, with
early development by myself in my spare time with assistance from Robin.
