In device tree environment, the previous code allocates
renesas_usbhs_platform_info by using devm_kzalloc() and then copies
usbhs_of_data to the allocated memory. This reason is some values
(e.g. .platform_callback.get_vbus) are overwritten by the driver,
but the of_device_id.data is "const". Now the driver doesn't have
such a code, so this patch uses renesas_usbhs_platform_info on
of_device_id.data.
Note that the previous code set the pdev->dev.platform_data pointer
even if device tree environment, but the value is not used. So,
this patch also remove such a code.

All platform related codes (rcar[23].c and rza{2}.c) has its own
.get_id function as "USBHS_GADGET". So, we can use a common
function for it.

Drop support for legacy phys for rcar2 which hasn't been used with a
mainline kernel since commit 9080b8dc76 ("ARM: OMAP2+: Remove legacy
usb-host.c platform init code"). Specifically, since that commit
usb_get_phy_dev() have always returned -ENODEV and consequently this
code has not been used.
Note that the legacy-phy API is still being used in gadget mode to bind
the peripheral controller.

Now that the SPDX tag is in all USB files, that identifies the license
in a specific and legally-defined manner. So the extra GPL text wording
can be removed as it is no longer needed at all.
This is done on a quest to remove the 700+ different ways that files in
the kernel describe the GPL license text. And there's unneeded stuff
like the address (sometimes incorrect) for the FSF which is never
needed.
No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to
audit the kernel tree for correct licenses.
Update the drivers/usb/ and include/linux/usb* files with the correct
SPDX license identifier based on the license text in the file itself.
The SPDX identifier is a legally binding shorthand, which can be used
instead of the full boiler plate text.
This work is based on a script and data from Thomas Gleixner, Philippe
Ombredanne, and Kate Stewart.
