V4L/DVB (9091): gspca: Subdriver m5602 (ALi) added. 

This patch adds support for the ALi m5602 usb bridge and is based on
the gspca framework.
It contains code for communicating with 5 different sensors:
OmniVision OV9650, Pixel Plus PO1030, Samsung S5K83A, S5K4AA and
finally Micron MT9M111.

This document describes the ALi m5602 bridge connected
to the following supported sensors:
OmniVision OV9650,
Samsung s5k83a,
Samsung s5k4aa,
Micron mt9m111,
Pixel plus PO1030
This driver mimics the windows drivers, which have a braindead implementation sending bayer-encoded frames at VGA resolution.
In a perfect world we should be able to reprogram the m5602 and the connected sensor in hardware instead, supporting a range of resolutions and pixelformats
Anyway, have fun and please report any bugs to m560x-driver-devel@lists.sourceforge.net
