USB: Add MSM OTG Controller driver
This driver implements PHY initialization, clock management, ULPI IO ops
and simple OTG state machine to kick host/peripheral based on Id/VBUS
line status. VBUS/Id lines are tied to a reference voltage on some boards.
Hence provide debugfs interface to select host/peripheral mode.
