Hello all,

I know this has been tried before[0], but given the recent upstreaming of
the Series6+ GPU bindings I figured it might be time to give the Series5
bindings another try.

While there is currently no mainline driver for these binding, there is an
open source out-of-tree kernel-side driver available[1]. Having a stable
and upstream binding for these devices allows us to describe this hardware
in device tree.

This is my vision for how these bindings should look, along with some
example uses in several SoC DT files. The compatible names have been
updated to match what was decided on for Series6+, but otherwise most
is the same as we have been using in our vendor tree for many years.

Thanks,
Andrew

Based on next-20231204.
