[v2,0/4] arm64: rockchip: Pine64 pinetab2 support

This adds support for the BOE TH101MB31IG002 LCD Panel used in Pinetab2 [1] and
Pinetab-V [2] as well as the devictrees for the Pinetab2 v0.1 and v2.0.

The BOE LCD Panel patch was retrieved from [3]. The function-name prefix has
been adapted and the LCD init section was simplified.

The Pinetab2 devicetree patch was retrieved from [4]. Some renaming was needed
to pass the dtb-checks, the brightness-levels are specified as range and steps
instead of a list of values.

[5] was also used as source for this queue.

The last to patches fix some dtb-checker warnings that showed up with the new
device-trees.
