minor GXL and GXM improvements

SCPI and SRAM are identical on GXBB and GXL. Moving the corresponding nodes to meson-gx adds support for the thermal sensor on GXL based devices.
While here, also rename the second compatible string because "arm,legacy-scpi" was replaced by "arm,scpi-pre-1.0".

This adds the SCPI DVFS clock index and configures the CPU cores accordingly.

This series adds SCPI support to GXL and GXM SoCs by moving the nodes to meson-gx.dtsi. Additionally this updates the compatible string to match the recent changes, see [0]

This series adds SCPI support to GXL and GXM SoCs by moving the nodes to meson-gx.dtsi.
Now that we have SCPI support for GXM we can also use it to configure the CPU cores using the SCPI DVFS clocks.

Changes since v1:
- added Tested-By and Acked-By tags from Neil Armstrong (thanks!)
- rebased to khilman/linux-amlogic.git/amlogic-dt64-2-v2
- updated description of patch 1 because the "arm,scpi-pre-1.0" change is already part of the amlogic-dt64-2-v2 tag
