xhci-pci: Make xhci-pci-renesas a proper modular driver

If CONFIG_USB_XHCI_PCI_RENESAS is enabled, xhci-pci conditionally
calls into the xhci-pci-renesas module, which means both modules must
be loaded to use any xHCI PCI controller.

The MODULE_FIRMWARE declaration in the base xhci-pci module causes
initramfs-tools to check for and warn about missing firmware for the
Renesas xHCI controllers, when any xHCI PCI controller is present.
And because of the previous oddity, simply moving this declaration to
xhci-pci-renesas wouldn't help.

To fix this, reverse the relationship between the modules:

- Remove the quirk for the Renesas xHCIs, and the driver_data
structure used only for them
- In xhci-pci:
- Rename xhci_pci_probe() to xhci_pci_common_probe()
- Export xhci_pci_common_probe() and xhci_pci_remove()
- Use a new probe function that rejects the Renesas xHCIs and then
calls the common probe function
- In xhci-pci-renesas:
- Stop exporting renesas_xhci_check_request_fw()
- Add a probe function that calls renesas_xhci_check_request_fw()
followed by xhci_pci_common_probe()
- Add and register a new pci_driver matching only the Renesas xHCIs
and using its own probe function, but with other operations the
same as in xhci-pci
- Make CONFIG_USB_XHCI_PCI_RENESAS depend on CONFIG_USB_XHCI_PCI,
not the other way around

Finally, move the MODULE_FIRMWARE declaration to xhci-pci-renesas.

usb: host: u132-hcd: Delete driver

This driver got its last actual change in 2006 and is probably unused as
nowbody should use a cardbus to USB adapter any more.

If it were still used, the driver was in urgent need for maintainer
love. (Explicit kref handling, underdocumented locking, .remove() can
return errors ...)

Also the link in the (now removed) help text doesn't look actively
maintained. According to archive.org it forwarded to
http://www.copenhagen-hotel.net/ already back in 2018.

So don't waste more time on this driver and just delete it.

xhci: split out rcar/rz support from xhci-plat.c

The USB_XHCI_RZV2M and USB_RENESAS_USB3 select other drivers
based on the enabled SoC types, which leads to build failures
when the dependencies are not met:

WARNING: unmet direct dependencies detected for USB_RZV2M_USB3DRD
Depends on [n]: USB_SUPPORT [=y] && USB_GADGET [=n] && (ARCH_R9A09G011 [=n] || COMPILE_TEST [=y])

ERROR: modpost: "rzv2m_usb3drd_reset" [drivers/usb/host/xhci-plat-hcd.ko] undefined!

The xhci-rcar driver has a reverse dependency with the xhci core, and it
depends on the UDC driver in turn. To untangle this, make the xhci-rcar.ko
driver a standalone module that just calls into the xhci-plat.ko module
like other drivers do.

This allows handling the dependency on the USB_RZV2M_USB3DRD driver to
only affect the xhci-rcar module and simplify the xhci-plat module.

It also allows leaving out the hacks for broken dma mask and nested
devices from the rcar side and keep that only in the generic xhci driver.

As a future cleanup, the marvell and dwc3 specific bits of xhci-plat.c
could be moved out as well, but that is not required for this bugfix.

usb: fotg210: Collect pieces of dual mode controller

The Faraday FOTG210 is a dual-mode OTG USB controller that can
act as host, peripheral or both. To be able to probe from one
hardware description and to follow the pattern of other dual-
mode controllers such as MUSB or MTU3 we need to collect the
two, currently completely separate drivers in the same
directory.

After this, users need to select the main symbol USB_FOTG210
and then each respective subdriver. We pave the road to
compile both drivers into the same kernel and select the
one we want to use at probe() time, and possibly add OTG
support in the end.

This patch doesn't do much more than create the new symbol
and collect the drivers in one place. We also add a comment
for the section of dual-mode controllers in the Kconfig
file so people can see what these selections are about.

Also add myself as maintainer as there has been little
response on my patches to these drivers.

usb: Introduce Xen pvUSB frontend (xen hcd)

Introduces the Xen pvUSB frontend. With pvUSB it is possible for a Xen
domU to communicate with a USB device assigned to that domU. The
communication is all done via the pvUSB backend in a driver domain
(usually Dom0) which is owner of the physical device.

The pvUSB frontend is a USB hcd for a virtual USB host connector.

The code is taken from the pvUSB implementation in Xen done by Fujitsu
based on Linux kernel 2.6.18.

Changes from the original version are:
- port to upstream kernel
- put all code in just one source file
- move module to appropriate location in kernel tree
- adapt to Linux style guide
- minor code modifications to increase readability

possible to do anything about the cyclic dependency of the Kconfig

by defconfigs and USB_GADGET is wanted on Tegra by default, hence it's
okay to have a bit clunky workaround for it.
