Great ... here's a small tweak, which you may want to just merge with the last one.

This contains two bugfixes to the initial twl4030 regulator support patch related to USB:
(a) always overwrite the old list of consumers ... else the regulator handles all use the same "usb1v5" name; (b) don't set up the "usbcp" regulator, which turns out to be managed through separate controls, usually ULPI directly from the OTG controller.
