[PATCHv2 1/3] dt-bindings: misc: achc: Make ezport distinguishable

[Sebastian Reichel]

This updates the GE ACHC binding, so that different compatible
strings are used for the programming interface, which is the
ezport interface from NXP MK20FN1M0VMD12 and the microcontroller's
normal SPI interface.
