usb: changes for v4.12
With 51 non-merge commits, this is one of the smallest USB Gadget pull
requests. Apart from your expected set of non-critical fixes, and
other miscellaneous items, we have most of the changes in dwc3 (52.5%)
with all other UDCs following with 34.8%.
As for the actual changes, the most important of them are all the
recent changes to reduce memory footprint of dwc3, bare minimum
dual-role support on dwc3 and reworked endpoint count and
initialization routines.
This patch splits the amd5536udc driver into two -- one that does
pci device registration and the other file that does the rest of
the driver tasks like the gadget/ep ops etc for Synopsys UDC.
This way of splitting helps in exporting core driver symbols which
can be used by any other platform/pci driver that is written for
the same Synopsys USB device controller.
The current patch also includes a change in the Kconfig and Makefile.
A new config option USB_SNP_CORE will be selected automatically when
any one of the platform or pci driver for the same UDC is selected.
Main changes:
- amd5536udc_pci.c: PCI device registration is moved to this file.
- amd5536udc.c:
This file does rest of the core UDC fucntionality.
9 symbols are exported so as to be used by amd5536udc_pci.c.
Module parameter definitions are moved to header file.
- amd5536udc.h:
Function declarations, module parameters definitions and few common
header file includes are added to this file
- Kconfig:
New USB_SNP_CORE option is added which will be auto selected when
any pci or platform driver config option for the UDC is chosen.
- Makefile:
Compiles the core and pci files separately.

The condition checking for irq_registered, regs, mem_region and active
are not required as this is the remove function. And we are in the
remove means that probe was successful and they can never be NULL at
this point of code.
It was required in the original code as the remove function was part of
the error handler of probe function.

The drivers/usb/gadget directory contains many files.
Files which are related can be distributed into separate directories.
This patch moves the UDC drivers into a separate directory.
