Thanks, will change like above.

These SoCs used the same FSL imx PHY, but different versions.
imx23/imx28 are the first version, more improvements are at
later SoCs (like imx6x) version. Keep "fsl,imx23-usbphy" at
imx6 dts will be user know it is from imx23's. If you think
it does not need, I can delete "fsl,imx23-usbphy" from imx6 dts.
