mfd: twl4030 regulator bug fixes
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.
