Add a compatible string for the Mali-450 GPU on Amlogic Meson8 and
Meson8b SoCs. Meson8 uses an "MP6" variant with six pixel processors
while Meson8b (as cost-reduced SoC) uses an "MP2" variant with two pixel
processors. Both have a reset line to bring the GPU into a well-defined
state.

Allwinner A64 has Mali-400MP2, so document the relevant compatible

As we move stuff around, some doc references are broken. Fix some of
them via this script:

Mali GPUs have a separate supplying regulator in a lot of socs,
so describe a mali-supply property. The already described
operating points will likely also need access to this regulator.

Some (older or lower power) Rockchip socs use Utgard-based Mali-GPUs.
So add the necessary compatibles for them. As the setup is the same for
all of them (needing only the additional reset line), they get added in
a somewhat condensed form, to not inflate the document unnecessary.

Allwinner H5 has a Mali-450 MP4 GPU, which has a reset line like other
Allwinner SoCs with Mali Utgard, but it's a Mali-450, so it needs a new
compatible.
Add the new compatible to Mali Utgard binding document.
