RE: multi-phy generic patch (Add plan)

Hi Felipe, Ajay, Kishon

In order to add generic USB PHY layer, from my point, below 
steps are needed to be done

1. Move generic PHY things from otg/ to phy/
	- Split include/linux/usb/otg.h to include/linux/usb/phy.h 
	and include/linux/usb/otg.h
      - Split drivers/usb/otg/otg.c to drivers/usb/otg/otg.c 
	and drivers/usb/phy/phy.c
	- Change CONFIG_USB_OTG_UTILS to CONFIG_USB_PHY_UTILS
	- obj-$(CONFIG_USB_OTG)           += otg.o
	- obj-$(CONFIG_USB_PHY)               += phy/

2. Eliminate the relationship between struct usb_otg and struct usb_phy

3. Add generic USB PHY layer support to drivers/usb/phy/phy.c
	- generic USB PHY layer is implemented at phy.c
	- Related driver's change for adopting this PHY layer

The step 2 is optional, and will take much time.

Any comments are welcome, I will begin step 1 from next week. 

Best regards,
Peter Chen
