Porting the cadence USB3 (CDNS3) driver from kernel to u-boot. We only support
the gadget (device mode), while the host mode is not supported. Users remains
to use xhci-imx8 driver for host mode.
Some changes in the CDNS3 driver porting:
1. Add match_ep call back to usb_gadget_ops. The CDNS3 gadget driver replies
on this operation to bind the usb_ep/usb_ss_ep with the endpoint descriptor
when function layer uses usb_ep_autoconfig to add endpoint descriptors to gadget.
So that CDNS3 driver can know the EP information and configure the EP once the
set configuration request is received.
2. U-boot does not have CMA, so it won't allocate uncached memory. Need to flush
TRB and its DMA buffer before prime to usb controller and after complete transfer.
3. In core.c, we add functions to hook with u-boot. It needs uplayer like
to pass the register base address of each part of the USB controller.
4. Force the CDNS3 gadget max speed to HS. The SuperSpeed is not supported by u-boot,
so disable it in gadget driver. A configuration USB_CDNS3_GADGET_FORCE_HIGHSPEED is
selected.
5. Added gadget_is_cdns3 checking to provide bcdUSB value in device descriptor.
6. Moved some new fields in usb_ep structure to usb_ss_ep, since u-boot does not have them.
7. Remove host part codes as it is not supported by this driver.

Since we support multiple dwc3 controllers to be existent at the same
time, in order to handle the interrupts of a particular dwc3 controller
usb_gadget_handle_interrutps should take controller index as an
argument.
Hence the API of usb_gadget_handle_interrupts is modified to take
controller index as an argument and made the corresponding changes to all
the usb_gadget_handle_interrupts calls.

Did a bunch of things to get dwc3/gadget.c compile in u-boot without
build errors and warnings
*) Changed the included header files to that used in u-boot.
*) Used dma_alloc_coherent and dma_free_coherent APIs of u-boot
*) removed sg support
*) remove jiffies and used a simple while loop
*) removed irq support and added a function to call these interrupt handler.

'bool' is defined in random places. This patch consolidates them into a
single header file include/linux/types.h, using stdbool.h introduced in C99.
All other #define, typedef and enum are removed. They are all consistent with
true = 1, false = 0.
Replace FALSE, False with false. Replace TRUE, True with true.
Skip *.py, *.php, lib/* files.
