Sebastian Reichel f9d8f4b313 dt-bindings: misc: ge-achc: Convert to DT schema format
Convert the binding to DT schema format. Also update the binding
to fix shortcomings

 * Add "nxp,kinetis-k20" fallback compatible
 * add programming SPI interface and reset GPIO
 * add main clock
 * add voltage supplies
 * drop spi-max-frequency from required properties,
   driver will setup max. frequency
