Commit 14485de431b0 ("usb: Use device_get_match_data()") overlooked the
already existing pointer to pdev-&gt;dev 'dev'.

Use the existing pointer 'dev' in device_get_match_data() to keep code
consistency.

The TI TUSB8020B is a 2-port USB 3.0 hub. Add support for
this hub in the driver in order to bring up reset, and supply
dependencies.

Power-up: Issue a GPIO reset (GRSTz) 3ms after VDD and VDD33 stabilize.

There is usbdrv_wrap in struct usb_driver and usb_device_driver, it
contains device_driver and for_devices. for_devices is used to
distinguish between device drivers and interface drivers.

Like the is_usb_device(), it tests the type of the device. We can test
that if the probe of device_driver is equal to usb_probe_device in
is_usb_device_driver(), and then the struct usbdrv_wrap is no longer
needed.

Clean up struct usbdrv_wrap, use device_driver directly in struct
usb_driver and usb_device_driver. This makes the code cleaner.

There is a general misunderstanding amongst engineers that {v}snprintf()
returns the length of the data *actually* encoded into the destination
array.  However, as per the C99 standard {v}snprintf() really returns
the length of the data that *would have been* written if there were
enough space for it.  This misunderstanding has led to buffer-overruns
in the past.  It's generally considered safer to use the {v}scnprintf()
variants in their place (or even sprintf() in simple cases).  So let's
do that.

Whilst we're at it, let's define some magic numbers to increase
readability and ease of maintenance.

The Cypress CY7C6563x is a 2/4-port USB 2.0 hub. Add support for
this hub in the driver in order to bring up reset, supply or clock
dependencies.

There is no reset pulse width given in the datasheet so we expect
a minimal value of 1us to be enough. This hasn't been tested though
due to lack of hardware which has the reset connected to a GPIO.

Most onboard USB hubs have a dedicated crystal oscillator but on some
boards the clock signal for the hub is provided by the SoC.

In order to support this, we add the possibility of specifying a
clock in the devicetree that gets enabled/disabled when the hub
is powered up/down.

Add support for the Microchip USB5744 USB3.0 and USB2.0 Hub.

The Microchip USB5744 supports two power supplies, one for 1V2 and one
for 3V3. According to the datasheet there is no need for a delay between
power on and reset, so this value is set to 0.
