[PATCH 2/3] ARM: OMAP1: Camera: Fix v4l2 int device detach

[Eduardo Valentin <edubezval@gmail.com>]

From: Eduardo Valentin <eduardo.valentin@indt.org.br>

camera_device_unregister expected the argument to be its own
device structure but it's actually that of its slave.

Also get master from slave's structure in camera_device_register.
