USB: twl4030: Enable USB regulators before enabling USB charging

For TWL family of power management ICs, USB charging works only
when USB regulators are in enabled state: 3v1, 1v5, 1v8

On a USB cable attach, twl4030_phy_resume(twl) function enables
the regulators. Enable USB charging, only after all regulators
are enabled.

Its observed that enabling USB charging before regulators are
enabled, causes USB charging to fail.

Tested on: Zoom2: omap3430: ES3.1 + TWL5030
Needs T2-MADC and T2-BCI drivers which are still not upstreamed.
