phy: usb-nop-xceiv: Add clock support ...

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

phy: Add usb-nop-xceiv support ...

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.
