FS #7691 - improved USB detection on PP devices. This patch modifies the target-tree function usb_detect() on all targets from bool to int, returning USB_INSERTED or USB_EXTRACTED instead of true or false. This was done to enable the PP usb_detect() to check for USB_POWER (either a connection to a USB wall charger, or the user holding "charge mode" button) and return that as a third value.
