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.

LoongArch: Migrate to the generic rule for built-in DTB2025-01-25T10:51:33ZMasahiro Yamada2025-01-25T10:51:33Zurn:sha1:c91ddab5799109124ccdfa88fd381c613a766a89
Commit 654102df2ac2 ("kbuild: add generic support for built-in boot
DTBs") introduced generic support for built-in DTBs.
Select GENERIC_BUILTIN_DTB when built-in DTB support is enabled.

The module is supported, adding it.

of enabling it:

LoongArch: Fix GMAC's phy-mode definitions in dts2024-06-03T07:45:53ZHuacai Chen2024-06-03T07:45:53Zurn:sha1:eb36e520f4f1b690fd776f15cbac452f82ff7bfa
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.

By now, more Loongson-2K2000 related drivers are supported, such as
clock controller and thermal controller. So we add these device nodes
to the Loongson-2K2000 dts file.

Things like clock controllers or architectural interrupt controllers,
no one would disable them because otherwise they would have no usable
system. So we just "enabled" them by default.
