Rock Pi N10 is a Rockchip RK3399Pro based SBC, which has

Carrier board often referred as baseboard. For making
complete SBC or any other industrial boards, these
carrier boards will be used with associated SOMs.

Radxa has Dalang carrier board which supports on-board
peripherals, ports like USB-2.0, USB-3.0, HDMI, MIPI DSI/CSI,
eDP, Ethernet, WiFi, PCIe, USB-C, 40-Pin GPIO header and etc.

Right now Dalang carrier board is used with two SBC-variants:
Rock Pi N10 => VMARC RK3399Por SOM + Dalang carrier board
Rock Pi N8  => VMARC RK3288 SOM + Dalang carrier board(+codec)

So add this carrier board dtsi as a separate file in
ARM directory, so-that the same can reuse it in both
rk3288, rk3399pro variants of Rockchip SOMs.

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

408MHz operating point for now.

Although it appeared to follow logically from the bindings, apparently
the thermal framework can't properly cope with a single cooling device
being shared between multiple maps. The CPU zone is probably easier to
overheat, so remove the references to the (optional) fan from the GPU
cooling zone to avoid things getting confused. Hopefully GPU-intensive
tasks will leak enough heat across to the CPU zone to still hit the
fan trips before reaching critical GPU temperatures.
