UPSTREAM: usb: dwc3-generic: Export glue structures and functions

In order to allow external SoC-dependent glue drivers to use dwc3-generic
functions, push the glue structures and export the functions to a header
file.

The exported structures and functions are:

- struct dwc3_glue_data
- struct dwc3_glue_ops
- dwc3_glue_bind()
- dwc3_glue_probe()
- dwc3_glue_remove()

The SoC-dependent glue drivers can only define their own wrapper driver
and specify these functions. The drivers can also add their own compatible
strings and configure functions.

UPSTREAM: usb: dwc3-generic: Allow different controller DT node pattern

The most of devicetree has the following USB node structure.
The controller node is placed as a child node of the glue node.
Current dwc3-generic driver works on this premise.

glue {
/* glue node */
usb {
/* controller node */
};
};

However, UniPhier original devicetree has the following USB node structure.
The controller node is separately placed from the glue node.

usb {
/* controller node */
};
glue {
/* glue node */
};

In dwc_glue_bind(), this patch provides .glue_get_ctrl_dev() callback to
get such a controller node and binds the driver related to the node.

If this callback isn't defined, dwc_glue_bind() looks for the controller
nodes from the child nodes, as before.

UPSTREAM: usb: dwc3-generic: add a new host driver that uses the dwc3 core

Currently the host driver used by dwc3-generic is "xhci-dwc3". This is
a functional driver but it doesn't use the dwc3 core and, in particular,
it lacks some bits that may be important.
For example on the k2 platforms, it is important that the phy are properly
suspended when the USB is not used anymore. The dwc3 core also has a
partial support for quirks.
The new driver can be used as a drop-in replacement for "xhci-dwc3".

In terms of implementation, it may seem strange that 2 private structures
dwc3_generic_host_priv and dwc3_generic_priv) are used. The reason for this
is simply that the xhci layer expects a struct xhci_ctrl at the beginning
of the private data and it seemed wasteful to include it also for the
peripheral case.
