Subject: [PATCH v2 14/20] dt-bindings: mtd: relax the nvmem compatible string

The "user-otp" and "factory-otp" compatible string just depicts a
generic NVMEM device. But an actual device tree node might as well
contain a more specific compatible string. Make it possible to add
more specific binding elsewhere and just match part of the compatibles
here.
