V4L/DVB (11351): v4l: use usb_interface for v4l2_device_register
If usb_interface.dev is used as dev parameter for v4l2_device_register v4l2_dev.name contains the v4l driver/module name and usb device and interface instead of a simple "usb x-y". It also matches the recommendation to set the parent devices for usb drivers. Signed-off-by: Janne Grunau <j@jannau.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

The first 'dev' argument is normally the struct device pointer of a pci_dev,

with ISA devices or when one device creates multiple PCI devices, thus making
it impossible to associate v4l2_dev with a particular parent.
