The vbus-regulator property was never actually read from the device tree.
Introduce a new property vbus-supply to represent the regulator powering
the VBUS when acting as an A-Device. This supply will be enabled and
disabled as necessary. Note that this is different from vbus-regulator,
which represented the available current available to draw from VBUS in
B-Device mode. Because no one was using vbus-regulator, remove it.
