Subject: [PATCH 4/4] dt-bindings: Remove PicoXcell bindings

PicoXcell has had nothing but treewide cleanups for at least the last 8
years and no signs of activity. The most recent activity is a yocto vendor
kernel based on v3.0 in 2015.

I'll take this via the DT tree.

Hi Rob,

(replying to an old patch that was applied a while ago)

Note that (a) the generic form is still used as the sole compatible
value in arch/arm64/boot/dts/lg/lg131[23].dtsi, and the Linux driver
matches against it, and (b) arch/arm/boot/dts/zynq-7000.dtsi uses
the generic form as a secondary compatible value.

Gr{oetje,eeting}s,

Geert
