Also known as Tegra X1+, the Tegra210B01 has higher CPU and GPU clocks
than the original Tegra210.
Add a SoC-level device tree file that describes most of the hardware
available on the SoC. This is derived from the Tegra210 dtsi, as they
share a lot.

The Tegra210 soc supports bpmp offload for power management among other
things. This was considered insecure partway through the soc's lifecycle
and support was removed in the bootloader. However, Tegra210B01 returned
to using the bpmp. Plus old bootloaders on the original Tegra210 still
work with the existing driver. So add the node to the common Tegra210
soc dtsi, but disabled by default.

Tegra210B01 uses Tegra186 style emc management, as in it is
offloaded to BPMP. This driver already implements this, so no
reason to shoehorn in elsewhere.

This is based on the downstream Nvidia 5.10 kernel. That version was
semi-integrated into the Tegra210 clock driver. Looking at the existing
Tegra210 support, it made more sense to make this a fully independent
driver, so that is implemented here.

These are generated by the Tegra210 Android bootloader. This is similar
to the Tegra124 handling, so the support is based on that and modified
to match Tegra210 by referencing the downstream Nvidia 4.9 kernel.

These entries are imported from the downstream Nvidia Linux4Tegra
kernel. They are expected to be updated with the trained values by the
bootloader. This is done by the Nvidia Android bootloader, which is
different from the handling by the Nvidia Linux bootloader which places
these values in a reserved memory location. P2180 is supported by both
bootloaders, so lets support initializing emc on both.
It should be noted that the bootloader will not create these nodes in
the kernel dtb if they do not exist. It will only set in place existing
properties.

This devkit is very similar to P3450, except it has less ram, no display
port, and only 3 usb host ports. Derive from P3450 and disable the
hardware that is unavailable.
Gpio PA6 is used to control the hdmi power rail and needs to be on for
hotplug detect to work. This is mapped to the 3.3V usb hub on P3450.
That usb rail is not used here, so delete the regulator to avoid
conflicts.
