We have an existing U-Boot header for the one function that this defines.
Use that instead of the linux/ one. Move over the nice comment.

U-Boot has two different variants of dwc3 initializations,
- with dm variant gadget, so the respective dm driver would
  call the dwc3_init in core.
- with non-dm variant gadget, so the usage board file would
  call dwc3_uboot_init in core.

The driver probe would handle all respective gadget properties
including phy interface via phy_type property and then trigger
dwc3_init for dm-variant gadgets.

So, to support the phy interface for non-dm variant gadgets,
the better option is dwc3_uboot_init since there is no
dedicated controller for non-dm variant gadgets.

This patch support for adding phy interface like 8/16-bit UTMI+
code for dwc3_uboot.

This change used Linux phy.h enum list, to make proper code
compatibility.

This patch changes ERR_PTR/PTR_ERR to use CONFIG_ERR_PTR_OFFSET to map
errno values into a pointer region that cannot contain valid pointers.

IS_ERR and IS_ERR_OR_NULL have to be converted to use PTR_ERR, too,
for this to work.

This patch was copied from kernel commit: 67fdfda4a99ed.

Sometimes, the gadget driver we want to run has max_speed lower than
what the UDC supports. In such situations, UDC might want to make sure
we don't try to connect on speeds not supported by the gadget
driver because that will just fail.

So here introduce a new optional ->udc_set_speed() method which can be
implemented by interested UDC drivers to achieve this purpose.

Add match_ep() op to usb_gadget_ops similar to Linux kernel which is
useful in finding a suitable ep match for the function driver. This will
avoid adding more gadget_is_xxx() handling code to usb_ep_autoconfig().

Also sync usb_ep_caps struct thats is usually used in the match_ep()
callback by the gadget controller driver
