[PATCH v2 7/8] dt-bindings: firmware: amlogic, scpi: Convert to json schema

[Sudeep Holla]

Convert/merge the existing text format SCPI binding additions for
amlogic,scpi into the common arm,scpi json scheme.

Couple of things to note:
"amlogic,meson-gxbb-scpi" is always used with "arm,scpi-pre-1.0" and
"amlogic,meson-gxbb-scpi-sensors" is used always with "arm,scpi-sensors"
