Dmitry Torokhov 76336b41bd Input: pxrc - flatten probe code
Instead of splitting probe code into separate USB and input setup, flatten it.
This allows for easier inspection of order of set up steps, since the probe code
is reasonably small.

Move input-related initialization (phys) from USB block to input block.

Dmitry Torokhov c8783d3930 Input: pxrc - do not store unneeded data in driver structure
There is no need to store data buffer size, pointer to the buffer, or endpoint
address in pxrc structure, as they are either only needed during setup, or are
available from elsewhere.

Dmitry Torokhov 34dad2cf11 Input: pxrc - fix freeing URB on device teardown
URB is the only resource that is not managed, and thus is destroyed too early,
before we unregister input device and stop URB in pxrc_close(). To fix it let's
install custom devm handler to free the URB at the right time in devm unwind
sequence.

Marcus Folkesson 9730f60888 Input: pxrc - do not store USB device in private struct
The USB device is only needed during setup, so put it back after
initialization and do not store it in our private struct.

Also, the USB device is a parent of USB interface so our driver
model rules ensure that USB device should not disappear while
interface device is still there; there is no need to take reference
to the USB device.
