[PATCH 1/2] ARM64: dts: Add support for Meson GXM

Neil Armstrong [off-list ref] writes:

Following the Amlogic Linux kernel, it seem the only differences
between the GXL and GXM SoCs are the CPU Clusters.

This commit renames the gxl-s905d-p23x DTSI in a common file for
S905D p20x and S912 q20x boards.

Then adds a meson-gxm dtsi and reproduce the P23x to Q20x boards
dts files since the S905D and S912 SoCs shares the same pinout
and the P23x and Q20x boards are identical.

Applied.

Git tip: for future reference, set 'git config diff.renames true' so and
the diffstat shows a better summary when files are moved/renamed.

e.g, rather than the large ++ and -- above, you'd see:

 ...gxl-s905d-p23x.dtsi => meson-gx-p23x-q20x.dtsi} |   4 +-
 
Which is much more comforting to a maintainer than a bunch of
(potentially unrelated) adds and removes.

Thanks,

Kevin
