52defe8f65 sunxi: musb: Check Vbus-det before enabling otg port power 
Sending out 5V when there is a charger connected to the otg port is not a
good idea, so check for this and error out.

Note this commit currently breaks otg support on the q8h tablets, as we need
to do some magic with the pmic there to get vbus info, this is deliberate
(better safe then sorry), fixing this is on my TODO list.

Peripheral mode needs us to signal vusb high to the phy for it to work,
just like the host mode does.

28a15ef7fd musb-new: Add sunxi musb controller support 
This is based on Jussi Kivilinna's work for the linux-sunxi-3.4 kernel to use
the kernels musb driver instead of Allwinners own custom driver.
