usb: xhci-plat: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart from
emitting a warning) and this typically results in resource leaks. To improve
here there is a quest to make the remove callback return void. In the first
step of this quest all drivers are converted to .remove_new() which already
returns void. Eventually after all drivers are converted, .remove_new() is
renamed to .remove().
To convert the xhci-plat driver, change the prototype of
xhci_plat_remove() to return void. As this function is exported and used
by the xhci-rcar driver, convert this driver at the same time
accordingly.
