The "reset-gpios" is optional in real case, for example reset pin is
is hard wired to "high". And this fact is also reflected by the
devm_gpio_get_optional() calling in driver code.

Documentation/process/license-rules.rst and checkpatch expect the SPDX
identifier syntax for multiple licenses to use capital "OR". Correct it
to keep consistent format and avoid copy-paste issues.
Correct also the format // -> .* in few Allwinner binding headers as
pointed out by checkpatch:

The VIA Lab VL817 is a USB 3.1 Gen 1 hub and USB 2.0 hub
controller that features 4 downstream ports and 1 otg, with
an internal 5V regulator and has external reset pin.
Add a device tree binding for its USB protocol part.
The internal LDO is not covered by this and can just be modelled
as a fixed regulator.
Add combo of USB 2.0 and USB 3.0 root hub using peer-hub.
