PCIe PHY needs different initialization on MT7628/MT7688 SoCs than it does
on MT7620.
However, LEDE (and OpenWRT) dts files have the PCIe node for MT7628/MT7688
as compatible with mt7620-pci.
We already can handle this properly in our driver, so we just need to add
compat strings to fbsd-mt7628an.dtsi and the PCIe driver.

This is an import of the reworked LEDE dts files. Besides other things
they make it easier for us to reuse.
The only diffs left are for the following SoCs:
MT7620A (fbsd-mt7620a.dtsi)
MT7621 (fbsd-mt7621.dtsi)
MT7628 (fbsd-mt7628an.dtsi)
RT3883 (fbsd-rt3883.dtsi)
So we include the fbsd-*.dtsi files at the end of the original LEDE dtsi
files, using '#include "fbsd-xxxx.dtsi"'.
For example, for MT7621, the LEDE dtsi file is mt7621.dtsi. At the end of
it we add:
#include "fbsd-mt7621.dtsi"

The A83T thermal sensor controller has three sensors. Sensor 0 corresponds
to CPU cluster 0, sensor 1 to CPU cluster 1, and sensor 2 to the GPU. This
driver exports the temperature sensor readings via sysctl.
Calibration data is obtained from SRAM found in the Secure ID module.

FDT overlays is de-facto standard for describing expansion boards like
Beaglebone capes or Raspberry Pi shields. The ides is to have basic
DTB for base board and overlays DTB for shields/capes and to construct
final DTB either using human-readable configuration or some
self-discovery mechanism. I believe this approach can also be expanded
to support dynamically loadable FPGA bitstreams on systems like
Zedboard/Zybo.
Overlaying process is simmilar to executable link process for
binaries: each DTB has "exported" symbols and "undefined" symbols, the
latter are resolved using information for the former obtained from
base DTB or one of the overlays applied earlier (more rare case).
This symbols information is not generated by standard dtc that FreeBSD
has in base system, patched[1] version required to produces
overlay-compatible blobs. So although DTB files generated by
buildkernel do not support overlays there are enough
vendor/community-provided DTB blobs ciruclating around to justify
committing this change to ubldr.
This commit introduces handler for "fdt_overlays" variable that can be
defined either as a loader env variable or U-Boot env variable.
fdt_overlays is comma-separated list of .dtbo files located in
/boot/dtb/ directory along with base .dtb. ubldr loads files and
applies them one-by-one to base .dtb and then passes result blob to
the kernel.

This revision suggests dtsi patches to be used with the original OpenWRT
dtsi files so we can re-use what has already been done in OpenWRT for the
Mediatek/Ralink SoCs.
The only thing that is required after importing this revision should be
the following:
1. Import OpenWRT dts/dtsi files into sys/gnu/dts/mips
2. Run the following script in sys/gnu/dts/mips:
for f in `ls [mr]t*.dtsi`; do
printf "\n#include <fbsd-$f>\n" > $f
done
This will apply our dtsi patches to OpenWRT's dtsi files and will allow us
to re-use dts/dtsi files for ~170 Mediatek/Ralink boards.
Currently our drivers are not 100% compatible with OpenWRT's dts files, but
they're compatible enough.
We can add more functionality in the future that would better leverage the
OpenWRT work as well.

The following pheripherals are supported: UART, MMC, AHCI, EHCI, PCIe, I2C,
PMIC, GPIO, CPU temperature and clock.
Note: The PCIe driver is pure mash at this moment. It will be reworked
immediately when both D5237 and D2579 enter the current tree.
After ARM_INTRNG introduction, MPIC code needed several modifications:
- IRQ resource and its handler added
- several DEVMETHODs of INTRNG interface implemented
- defines enhanced to ensure code compiles as well for AXP as for A38X
- added dummy MSI_IRQ, ERR_IRQ defines for Armada38x
- MPIC driver was added to files.armada38x, ARM_INTRNG option enabled in
kernconf file and regs of MPIC corrected in dts file.
Instead of modifying Armada38X DTS, offsets to CPU registers defined in
driver were changed. That required restoring 'reg' property of mpic node
in ArmadaXP to state compliant with Linux DTS.
Additionally, required ARM_INTRNG definitions were added to mv_common.c.

This is not properly respecting WITHOUT or ARCH dependencies in target/.
Doing so requires a massive effort to rework targets/ to do so. A
better approach will be to either include the SUBDIR Makefiles directly
and map to DIRDEPS or just dynamically lookup the SUBDIR. These lose
the benefit of having a userland/lib, userland/libexec, etc, though and
results in a massive package. The current implementation of targets/ is
very unmaintainable.
