usb: phy: ab8500-usb: fix last notifier arguments 

Fix last ab->phy.notifier call to use vbus_draw as notifier argument, as
that's used in ab8500_charger to control charging current.

Also drop a related TODO comment, and the additional
ux500_musb_set_vbus(musb, 0), as with this patch it was causing an
erratic behaviour of gadget ep0 state machine.
