usb: udc: dwc3: Fold board dm_usb_gadget_handle_interrupts() into DWC3 gadget

The dm_usb_gadget_handle_interrupts() has no place in board code. Move
this into DWC3 driver. The OMAP implementation is special, add new weak
dwc3_uboot_interrupt_status() function to decide whether DWC3 interrupt
handling should be called, and override it in OMAP DWC3 code, to repair
the special OMAP interrupt handling code until OMAP gets switched over
to DM UDC proper.

board: usb: Replace legacy usb_gadget_handle_interrupts()

The usb_gadget_handle_interrupts() is no longer used anywhere,
replace the remaining uses with dm_usb_gadget_handle_interrupts()
which takes udevice as a parameter.

Some of the UDC drivers currently ignore the index parameter altogether,
those also ignore the udevice and have to be reworked. Other like the
dwc3_uboot_handle_interrupt() had to be switched from index to udevice
look up to avoid breakage.

SPDX: Convert all of our single license tags to Linux Kernel style

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from. So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry. Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents. There's also a few places where I found we did not have a tag
and have introduced one.
