The binding wants the node to be named "i2c-number", but those are named
"i2c-gpio-number" instead.
Thus rename those to i2c-0, i2c-1 to adhere to the binding and suppress
dtbs_check warnings.

SoC integrated peripherals on LS2K1000 and LS2K2000 could be discovered
as PCI devices, but require sideband interrupts to function, which are
previously described by interrupts and interrupt-parent properties.
However, pci/pci-device.yaml allows interrupts property to only specify
PCI INTx interrupts, not sideband ones. Convert these devices to use
interrupt-extended property, which describes sideband interrupts used by
PCI devices since dt-schema commit e6ea659d2baa ("schemas: pci-device:
Allow interrupts-extended for sideband interrupts"), eliminating
dtbs_check warnings.

The 2k1000 reference boards do not have a Rohm DAC on them as far as I
can tell, and they certainly do not have a dh2228fv, as this device does
not actually exist! Remove the dac nodes from the devicetrees as it is
not acceptable to pretend to have a device on a board in order to bind
the spidev driver in Linux.

The GMAC of Loongson chips cannot insert the correct 1.5-2ns delay. So
we need the PHY to insert internal delays for both transmit and receive
data lines from/to the PHY device. Fix this by changing the "phy-mode"
from "rgmii" to "rgmii-id" in dts.

During the upstream progress of those DT-based drivers, DT properties
are changed a lot so very different from those in existing bootloaders.
It is inevitably that some existing systems do not provide a standard,
canonical device tree to the kernel at boot time. So let's provide a
device tree table in the kernel, keyed by the dts filename, containing
the relevant DTBs.
We can use the built-in dts files as references. Each SoC has only one
built-in dts file which describes all possible device information of
that SoC, so the dts files are good examples during development.
And as a reference, our built-in dts file only enables the most basic
bootable combinations (so it is generic enough), acts as an alternative
in case the dts in the bootloader is unexpected.
