[PATCH 2/2] gspca pac7302: remove LED blinking when switching stream on and off

["Németh Márton" <nm127@freemail.hu>]

From: Márton Németh <nm127@freemail.hu>

The init sequences for PAC7302 contained register settings affecting
the LED state which can result blinking of the LED when it is set to
always on or always off. The blinking happened when the stream was
switched on or off.

Remove the register changes from the init sequence and handle it with
the function set_streaming_led().
