[PATCH RESEND v5 1/4] dt-bindings: mtd: raw-nand-chip: Relax node name pattern

From: "J. Neuschäfer" <redacted>

In some scenarios, such as under the Freescale eLBC bus, there are raw
NAND chips with a unit address that has a comma in it (cs,offset).
For reasons of compatibility with historical device trees and
readability of the unit addresses, this format is kept.

Relax the $nodename pattern in raw-nand-chip.yaml to allow such unit
addresses. Unfortunately $nonenames defined in bindings that reference
raw-nand
