Can't you add 'fsl,imx7d-usb' here and drop the previous if/then?

With that,

If I do this I need to remove 'fsl,imx7d-usb' again in patch 06/11.
(KK said I'd not better do that)
Because imx93 is compatible with imx7d in non-wakeup case, but
imx93 need one wakeup clock to support wakeup feature. Here 'contains'
'fsl,imx7d-usb' will include both imx7d and imx7d compliant socs.

Thanks,
