V4L/DVB (5024): Fix quickcam communicator driver for big endian architectures

Host endianess does not affect the order that pixel rgb data comes
in from the quickcam (the values are bytes, not words or longs). The
driver is erroniously swapping the order of rgb values for big endian
machines. This patch is needed get the Quickcam communicator working
on big endian machines (tested on powerpc)
