When adding indirect (2 level) tabled we will need to know the page
size to calculate the size of the level 1 table. To allow for this find
the page size before entering the loop to calculate the final register
value.

For amd64, i386, arm, and riscv, i.e. all architectures except arm64,
the custom implementation is provided since we maintain the bitmask of
active CPUs anyway.
Arm64 uses somewhat naive iteration over CPUs and match current vmspace'
pmap with the argument. It is not guaranteed that vmspace->pmap is the
same as the active pmap, but the inaccuracy should be toleratable.

This basic version of the driver obtains properties of the "sff,sfp"
compatible devices and implements a simple interface to provide an I2C
bus device for the rest of the drivers (e.g. to implement SIOCGI2C).
Both of the interface and driver are subjects for a further
generalization to be used in case of non-FDT and non-arm64 platforms.

Add a driver to connect vt to the VirtIO GPU device in 2D mode. This
provides a output on the display when a qemu virtio gpu device is
added, e.g. with -device virtio-gpu-pci.
Tested on qemu using UTM, and a Hetzner arm64 VM instance.

As in commit 9051987e40 for amd64, support up to 1024 CPU cores.
arm64 hardware with more than 256 CPU cores is currently available and
will become increasingly common over FreeBSD 14's lifetime.

The gic driver is also probed at this pass and depending on the order of
the nodes in the dts rk_i2c can be probed first and will fail, this is the
case for the rk3328 SoC.
The PMIC drivers are also probed at this pass but on the iicbus which is created
in rk_i2c so there is no order conflict here.

We need i2c first to set it to MIDDLE, then we need one of the pmics
so set them to LATE, only then we can attach iodomain which needs some
regulators exposed by the pmic so set it to LAST.

We create a static array of pointers to per-CPU data. Because the cpuid
space on arm64 is not sparse there is no need to add an extra level of
indirection. Move to use mallocarray to allocate the redistributors as
a single array.
