usb: musb: omap2430: propagate PHY setup errors

The OMAP2430 glue ignores generic PHY initialization and power-on failures during initial setup, runtime resume and system resume. The callers can therefore access glue registers or publish resumed state without a usable PHY.

Keep the three lifecycle transitions separate so each patch has one failure state and one introducing commit. Each power-on failure exits a PHY that was initialized by the same transition.

The issues were found by our static-analysis tool and manually reviewed.
