Fix build errors that happen when CONFIG_EXTCON=m and
CONFIG_USB_SNP_UDC_PLAT=y by preventing that combination in Kconfig.
CONFIG_EXTCON can still be disabled or enabled for this driver since
<linux/extcon.h> has stubs for the disabled case, but if CONFIG_EXTCON=m,
USB_SNP_UDC_PLAT is restricted to m or n (cannot be builtin).

As USB_SNP_CORE is selected by USB_SNP_UDC_PLAT and USB_AMD5536UDC,
these should depend on HAS_DMA, too. For USB_AMD5536UDC, this is
already fulfilled through the dependency on USB_PCI (PCI implies
HAS_DMA).
Add dependencies on HAS_DMA to fix this.

This patch adds platform driver support for Synopsys UDC.
A new driver file (snps_udc_plat.c) is created for this purpose
where the platform driver registration is done based on OF
node.
Currently, UDC integrated into Broadcom's iProc SoCs (Northstar2
and Cygnus) work with this driver.
New members are added to the UDC data structure for having platform
device support along with extcon and phy support.
Kconfig and Makefiles are modified to select platform driver for
compilation.

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.

This patch updates the usb endpoint allocation scheme for atmel usba
driver to make sure all endpoints are allocated in order. This
requirement comes from the datasheet of the controller.
The allocation scheme is decided by fifo_mode parameter. For fifo_mode =
0 the driver tries to autoconfigure the endpoints fifo size. All other
modes contain fixed configurations optimized for different purposes. The
idea is somehow similar with the approach used on musb driver.

The USB_FSL_MPH_DR_OF symbol is used to ensure the code that interprets
the DR device node is built whenever one of the two drivers (EHCI or
UDC) for the platform is enabled. However, if CONFIG_USB is disabled
and we only support gadget mode, this causes a Kconfig warning:
warning: (USB_FSL_USB2) selects USB_FSL_MPH_DR_OF which has unmet direct dependencies (USB_SUPPORT && USB)
We can avoid this warning by simply no longer using the symbol,
and making sure we enter the drivers/usb/host/ directory when
the UDC driver is enabled that needs the file, and then we use
Makefile syntax to ensure the file is built-in if needed.
There is currently a dependency on CONFIG_OF, but this is redundant,
as we already know that this is set unconditionally for the platforms
that use this driver.

On checking the code it turned out that if CONFIG_OF is defined then it
is using at91_pmc_read() which is using at91_pmc_base. And unless
COMMON_CLK_AT91 is defined we donot have at91_pmc_base. And
COMMON_CLK_AT91 is available with AT91 architecture.

Pull kconfig updates from Michal Marek:

this hasn't happened. So I'm sending a few kconfig patches that I
collected:
- Fix for missing va_end in kconfig
- merge_config.sh displays used if given too few arguments
- s/boolean/bool/ in Kconfig files for consistency, with the plan to
only support bool in the future"
* 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild:
kconfig: use va_end to match corresponding va_start
merge_config.sh: Display usage if given too few arguments
kconfig: use bool instead of boolean for type definition attributes
Since non-DT board support has been removed from the at91 architecture we
can safely remove non-DT handling code.
