dt-bindings: Remove Linuxisms from common-properties binding

We shouldn't reference Linux kernel functions or Linux itself in proper
bindings. It's OK to reference functions in the kernel when explaining
examples, but otherwise we shouldn't reference functions to describe
what the binding means.

 The Devicetree Specification does not define any properties related to hardware

 Optional properties:

  - native-endian: Boolean; always use register accesses matched to the

    will ever be performed.  Use this if the hardware "self-adjusts"
    register endianness based on the CPU's configured endianness.
 
 If a binding supports these properties, then the binding should also
 specify the default behavior if none of these properties are present.
