[PATCH 1/4] dt-bindings: memory: additional compatible strings for Broadcom DPFE

[Markus Mayer]

Add versioned compatible strings for Broadcom DPFE. These take the form
brcm,dpfe-cpu-v<N> where <N> is a number from 1 to 4.

These API version related compatible strings are more specific than the
catch-all "brcm,dpfe-cpu" and more generic than chip-specific compatible
strings.
