It looks like the px30 is running unstable at this 408MHz operating point.
This shows in stalled threads and other big numbers of kernel exception.
At 600MHz and above it instead works stable and as expected. As the 408MHz
point doesn't even decrease the voltage compared to 600MHz, just drop this
408MHz operating point for now.

Having a default optee node in a soc devicetree is not really good.
For one there is no guarantee that any tee got loaded and there's even
the possibility that a completely different TEE got loaded.
OP-Tee however will insert relevant nodes to the devicetree (firmware
+reserved memory sections) during its own startup, so there really is
no need to provide a default node.

The px30 soc contains a controller for one-time-programmable memory,
so add the necessary node for it and the fields defined in it by default.

The px30 contains 2 separate clock controllers the regular cru creating
most clocks as well as the pmucru managing the GPLL and some other clocks.
The gpll of course also is needed by the cru, so while we normally do rely
on clock names to associate clocks getting probed later on (for example
xin32k coming from an i2c device in most cases) it is safer to declare the
explicit dependency between the two crus. This makes sure that for example
the clock-framework probes them in the correct order from the start.
The assigned-clocks properties were simply working by chance in the past
so split them accordingly to the 2 crus to honor the loading direction.

These are unused gpio-settings for specific function pins, that
are not used by anything and only clutter up the dtsi.
They can be re-added when a relevant user is added.

emmc chips are normally hooked up in standard ways using the full 8bit
bus connection, so there should be no need for all future boards to define
this on their own. So add default pin setups for 8bit busses and special
boards really only needing 4 or 1 bit connections can override.

Similar to all other Rockchip SoCs the px30 does not have a static
32kHz clock. Instead it again gets supplied from an external component
like the pmic.
So drop the static clock, so that we can hook up the right one.

The 'arm,armv8' compatible string is only for software models. It adds
little value otherwise and is inconsistently used as a fallback on some
platforms. Remove it from those platforms.
This fixes warnings generated by the DT schema.
