The compatible string for the Tegra210 APBMISC block was missing from
the bindings. Add it and while at it, rewrite the description of the
compatible string to make it clearer.

Note that this actually changes the compatible string for Tegra132 to
reflect what current device trees actually ship with.

The NVIDIA Tegra234 VDK is a simulation platform for the Orin SoC. It
supports a subset of the peripherals that will be available in the final
chip and serves as a bootstrapping platform.

This function extracts the PRE_SI_PLATFORM field from the HIDREV
register and can be used to determine which platform the kernel runs on
(silicon, simulation, ...). Note that while only Tegra194 and later
define this field, it should be safe to call this on prior generations
as well since this field should read as 0, indicating silicon.

The MISC block is largely similar to that found on earlier chips, but
not completely compatible. Allow binding to the instantiation found on
Tegra234.

From: Thierry Reding <treding@nvidia.com>
Enable support for the BPMP on Tegra234 to avoid relying on Tegra194
being enabled to pull in the needed OF device ID table entry.
On simulation platforms the BPMP hasn't booted up yet by the time we
probe the BPMP driver and the BPMP hasn't had a chance to mark the
doorbell as ringable by the CCPLEX. This corresponding check in the
BPMP driver will therefore fail. Work around this by disabling the
check on simulation platforms.

supports a subset of the peripherals that will be available in the final
chip and serves as a bootstrapping platform.
