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.

Rely on platform_data being passed through auxdata for now; more elaborate
bindings for phy config and tunings to be added.

v2: moved vbus-gpio check to the helper function, added check for !of_node,
    added usb2 clock to board-dt table.

The two first HC capability registers (CAPLENGTH and HCIVERSION)
are defined as one 8-bit and one 16-bit register. Most HC
implementations have selected to treat these registers as part
of a 32-bit register, giving the same layout for both big and
small endian systems.

This patch adds a new quirk, big_endian_capbase, to support
controllers with big endian register interfaces that treat
HCIVERSION and CAPLENGTH as individual registers.

The Tegra2 USB controller doesn't properly deal with misaligned DMA
buffers, causing corruption.  This is especially prevalent with USB
network adapters, where skbuff alignment is often in the middle of a
4-byte dword.

To avoid this, allocate a temporary buffer for the DMA if the provided
buffer isn't sufficiently aligned.

The Tegra 2 SoC has 3 EHCI compatible USB controllers. This patch adds
the necessary glue to allow the ehci-hcd driver to work on Tegra 2
SoCs.

The platform data is used to configure board-specific phy settings and
to configure the operating mode, as one of the ports may be used as a otg
port. For additional power saving, the driver supports powering down the
phy on bus suspend when it is used, for example, to connect an internal
device that use an out-of-band remote wakeup mechanism (e.g. a gpio).
