musb can be suspended at the time some other driver wants to do ulpi
transfers using usb_phy_io_* functions, and that can cause data abort,
as it happened with isp1704_charger:
http://article.gmane.org/gmane.linux.kernel/1226122

Add pm_runtime to ulpi functions to rectify this. This also adds io_dev
to usb_phy so that pm_runtime_* functions can be used.

This changes the otg functions so that they receive struct
otg instead of struct usb_phy as parameter and
converts all users of these functions to pass the otg member
of their usb_phy.

Includes fixes to IMX code from Sascha Hauer.

All the drivers are now converted to use struct usb_otg, so
removing the OTG specific members from struct usb_phy.

Introducing struct otg and collecting otg specific members
to it from struct usb_phy. There are no changes to
struct usb_phy at this stage. This also renames
transceiver specific functions, and offers aliases for the
old otg ones.

Commit 3dacdf11 "usb: factor out state_string() on otg drivers"
broke building musb drivers since there is already another
otg_state_string() function in musb drivers, but with different
prototype. Fix musb drivers to use common otg_state_string(), too.

Also provide a nop for otg_state_string() if CONFIG_USB_OTG_UTILS
is not defined.

Save the last event in the otg_transceiver so that it can used in the
musb driver and gadget driver to configure the musb and enable the
vbus for host mode and OTG mode, if the device is connected during boot.
