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.

This new set of tracepoints will help all gadget
drivers and UDC drivers when problem appears. Note
that, in order to be able to add tracepoints to
udc-core.c we had to rename that to core.c and
statically link it with trace.c to form
udc-core.o. This is to make sure that module name
stays the same.

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.
