As per the schematic Monolithic Power Systems MP2161GJ-C499
supply a fixed output voltage of 5.0V. This supplies linked
to VDD_EE, HDMI_P5V0, USB_POWER, VCCK, VDDIO_AO1V8, VDDIO_AO3V3,
VDD3V3, DDR3_1V5 according to the schematics.

Rebased on linux-next.
Added Acked by Martin.
Fixed the commit message to add misssing VDDIO_AO3V3 and VDD3V3.

nit-pick: should be "schematics"
I hope that Kevin can fix that up when applying

usb_otg bus needs to get initialize from the u-boot to be configured
to used as power source to SBC or usb otg port will get configured
as host device. Right now this support is missing in the u-boot and
phy driver so to avoid power failed warning, we would disable this
feature until proper fix is found.

Earlier my approach to initialize the usb0 bus was limited, some more
phy tuning is required both at driver and u-boot to get this feature
working. So for now just disable this.
