Introduce fdt_ether_get_addr() in fdt_common.c/h that tries standard
DT properties in the correct order and falls back to a random address
when needed. This should be used by ethernet drivers instead of open-coding
the same logic.

static dtb: add BTI note2026-03-05T08:50:26ZRuslan Bukinbr@FreeBSD.org2026-03-05T08:50:18Zurn:sha1:dff2758b5fa7d4987b03f3a04e1b02b367fe9b73
Add BTI note to fdt_static_dtb.o
- resolves "Branch Target Exception" panic on FDT systems with static DTB
due to missing landing pads (bti note has to be in all object files used
for linkage)
- also required by bti_report linker feature

bus_alloc_resource: Pass rid by value to BUS_ALLOC_RESOURCE DEVMETHOD2025-12-09T20:00:06ZJohn Baldwinjhb@FreeBSD.org2025-12-09T19:59:21Zurn:sha1:575639548cef58590a1d70c29e47aae0e8d44153
The wrapper functions such as bus_alloc_resource_any() still support
passing the rid by value or pointer, but the underlying implementation
now passes by value.

dev/fdt: Add support for non-PCI MSI interrupts2025-11-18T18:00:30ZAndrew Turnerandrew@FreeBSD.org2025-11-18T18:00:30Zurn:sha1:68e6422c6c91170a615e77028683a157e8e39d05
Some non-PCI devices can send interrupts, e.g. the Arm SMMU or GICv5
Interrupt Wire Bridge. Add support for these by implementing pci_get_id
and pci_alloc_msi and the MSI/MSI-X parts of the PCIB interface.
Only the MSI parts of the PCI interface are added as that is all I am
able to test.

It was last used in virtio_mmio. As it appears to have been used for
cross referencing devices and the existing xref support should be used
in new code it can be removed.

Since only 32bits of the values are read from the fdt, the existing values
can compromise the results.
Fixes the boot on the Netgate 3100.

fdt_immr_* are only used by the armv7 Marvell code. Move setting the
variables there as no new code should need to set them.
