Previously this was worked around in the phy-sun4i-usb driver, which needed to sense VBUS changes and report them to the musb driver in a timely matter. However this workaround was only for the A31 and A33 type USB PHYs. To support newer platforms we would have to enable it for almost all the post-A31 SoCs. However, since this is actually the result of the PMIC's behavior, the workaround would be better if done in the PMIC driver, in this case the VBUS power supply driver. Add the same workqueue-based polling to the VBUS power supply driver. The polling interval is chosen to be the debounce interval from the USB PHY driver, as this short interval is needed in some cases, but the power supply driver would not know when.
