Allow musb_platform_enable to return an error code and propagate it up to usb_lowlevel_init().
This allows moving the checks for an external vbus being present to be moved from platform_init to platform_enable, so that the user can unplug a charger, plug in a host adapter with a usb-device, do a "usb reset" and have things working.
This also allows adding a check for the id-pin to platform_enable, so that it can short circuit the 1s delay in usb_lowlevel_init() when no host cable is plugged in and thus waiting for a device to show up is useless.
Note that all the changes to code shared with the kernel are wrapped in the kernel.
