dt-bindings: mtd: avoid automatically select from mtd.yaml

The mtd binding is always $ref'ed by other bindings, default selector
should be from other binding files which ref'ed it. Now, "$nodename" in
mtd.yaml turns into a "select" automatically such that a few binding check
issues reported because it conflicts with sram devices(eg, qcom,imem.yaml,
rules in folder sram/*)

To avoid the automatically created "select" in mtd.yaml, adding:

select: false
