Register backup function can be called from atomic context. Instead
of using atomic memory pool, embed backup storage space in
struct dwc2_hsotg.
Also add a valid flag in each struct as NULL pointer can't be used as
the content validity check any more.

dwc2 may not be able to exit from hibernation if the hardware
does not provide a way to detect resume signalling in this state.
Thus, add the possibility to disable hibernation feature.

As dwc2 pci module is now exporting dwc2 platform device, include
platform.o in dwc2-y and remove USB_DWC2_PLATFORM configuration
option. Driver will be built as two modules, dwc2.ko and dwc2_pci.ko.
dwc2.ko is the new platform driver.
Remove all EXPORT_SYMBOL_GPL as they are not needed any more.

So the parameters can be used in both host and gadget modes.
Also consolidate param functions in the core.h

This is required due to an Intel specific hardware issue. Where id-
pin setup causes glitches on the interrupt line when CONIDSTSCHG
interrupt is enabled.
Specify external_id_pin_ctl when an external driver (for example phy)
can handle id change, so that CONIDSTSCHG interrupt can be disabled
from the controller.

When suspending usb bus, phy driver may disable controller power.
In this case, registers need to be saved on suspend and restored
on resume.

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.

Clip max_transfer_size to 65535 for host. dwc2_hc_setup_align_buf()
allocates coherent buffers with this size, and if it's too large we
can exhaust the coherent DMA pool.
Tested on Raspberry Pi and Altera SOCFPGA.

According to the "dr_mode", the otg controller can work as
device role and host role. Some boards always want to use host mode
and some other boards want to use gadget mode. We use the dts setting
to set dwc2's mode, rather than fixing it to whatever hardware says.

The documentation for GNPTXFSIZ says that "For host mode, this field
is always valid." Since we're already switching to host mode for
HPTXFSIZ, let's also read GNPTXFSIZ in host mode.
On an rk3288 SoC, without this change we see this at bootup:
dwc2 ff580000.usb: gnptxfsiz=00100400
dwc2 ff580000.usb: 128 invalid for host_nperio_tx_fifo_size. Check HW configuration.
After this change we see:
dwc2 ff580000.usb: gnptxfsiz=04000400

The dwc2 IP on the SOCFPGA cannot use the default HW configured
FIFO sizes. The total FIFO depth as read from GHWCFG3 reports 0x1f80 or 8064
32-bit words. But the GRXFSIZ, GNPTXFSIZ, and HPTXFSIZ register defaults
to 0x2000 or 8192 32-bit words. So the driver cannot just use the fifo sizes
as read from those registers.
For platforms that face the same issue, this commits sets the RX, periodic TX,
and non-periodic TX fifo size to those that are recommended v2.93a spec for
the DWC2 IP. Implements Method #2 from the Synopsys v2.93a spec for the DWC2.

Commit beb7e592bc "staging: dwc2: add check on dwc2_core_reset
return" broke the B -> A role switching on OTG-enabled platforms.
This commit fixes it.

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.
