This commmit is the result of running checkpatch --fix.
The results were verified for correctness. Some of the fixes result in
line over 80 char which we will fix manually later.
The following is a summary of what was done by checkpatch:
* Remove externs on function prototypes.
* Replace symbolic permissions with octal.
* Align code to open parens.
* Replace 'unsigned' with 'unsigned int'.
* Remove unneccessary blank lines.
* Add blank lines after declarations.
* Add spaces around operators.
* Remove unnecessary spaces after casts.
* Replace 'x == NULL' with '!x'.
* Replace kzalloc() with kcalloc().
* Concatenate multi-line strings.
* Use the BIT() macro.

This is not needed as the gadget now fully supports DMA and it can
autodetect it. This was initially added because gadget DMA mode was only
partially implemented so could not be automatically enabled.

Add device parameters handling in dwc2-pci similar what is done in dwc3.

The pci driver now registers a platform driver, like in dwc3, and lets
its probe function do all the initialization. This allows it to
account for changes to the platform driver that were not added to the
pci driver. Also future changes to the probe function don't have to be
duplicated. This also has the effect of adding device and DRD mode to
the pci driver. Tested on the Synopsys HAPS PCIe platform.

Removed FIXME from usb/dwc3/dwc3-pci.c by moving definition of
PCI_VENDOR_ID_SYNOPSYS shared with usb/dwc2 to linux/pci_ids.h.

Make dwc2_handle_common_intr call the gadget interrupt function when operating
in peripheral mode. Remove the spinlock functions in s3c_hsotg_irq as
dwc2_handle_common_intr() already has the spinlocks.
Move the registeration of the IRQ to common code for platform and PCI.
Remove duplicate interrupt conditions that was in gadget, as those are handled
by dwc2 common interrupt handler.

This patch will aggregate the probing of gadget/hcd driver into platform.c.
The gadget probe funtion is converted into gadget_init that is now only
responsible for gadget only initialization. All the gadget resources are now
handled by platform.c
Since the host workqueue will not get initialized if the driver is configured
for peripheral mode only. Thus we need to check for wq_otg before calling
queue_work().
Also, we move spin_lock_init to common location for both host and gadget that
is either in platform.c or pci.c.
We also move suspend/resume code to common platform code.
Lastly, move the "samsung,s3c6400-hsotg" binding into dwc2_of_match_table.

The DWC2 driver should now be in good enough shape to move out of
staging. I have stress tested it overnight on RPI running mass
storage and Ethernet transfers in parallel, and for several days
on our proprietary PCI-based platform.
