Address the device tree check warning: "phy@4c1f0040 (fsl,imx95-usb-phy):
fsl,phy-pcs-tx-deemph-3p5db-attenuation-db: 17 is not of type 'array'"

And dt_binding_check reports:
properties:fsl,phy-pcs-tx-deemph-3p5db-attenuation-db: '$ref' should not be
valid under {'const': '$ref'}
hint: Standard unit suffix properties don't need a type $ref

So remove ref for fsl,phy-pcs-tx-deemph-3p5db-attenuation-db.
