USB: otg: twl4030: fix wrong assumption of starting state
The reset state of twl4030-usb is not sleeping, it starts
up awaken and we need to disable it if we have booted
with a disconnected cable to avoid over consumption on
the default state.
To avoid problems later, we read the current state of the
transceiver from the PHY_PWR_CTRL register. The bootloader
can, anyways, put the device to sleep before us.
Tested on a custom OMAP board.
