As stated in the FIXME comment this is needed. Get and
enable a "main_clk" just like the kernel does.

Add a nop usb transcveiver driver. At the moment it does nothing,
so is nothing more than a driver to satisfy the device tree
dependencies. clk / vbus-regulator / vbus-detect-gpio support can be
added later.

The generic phy support layer has the necessary list handling
and phy retrieval functions, so we should reuse them for usb
phys. This adds a phy_to_usbphy() conversion function which
drivers can implement which attach to the generic phy layer
and are really usb phys.

Currently generic phy support assumes that the standard phy binding from
dts/Bindings/phy/phy-bindings.txt is used. This adds a helper function
which can be used to retrieve a phy when this standard binding is not
used.

This brings in the generix PHY framework from Linux.
I tried to strip it down as much as possible while
keeping it useful.
