V4L/DVB: Deprecate cpia driver (used for parallel port webcams)

Browse Source 
cpia driver were re-written inside gspca driver, for USB devices. The only
functionality that were not migrated is the support for parallel port,
as:
	1) the developer didn't find any hardware;
	2) it doesn't  seem important to keep support for a parallel port webcam,
	   as this is an obsolete technology;
	3) the changes at gspca for it to work with parallel port would be very large;
	4) this driver still uses BKL.

So, let's move it to drivers/staging and label it to die at 2.6.38, if nobody
cares enough to port parallel port support to gspca or to create a new driver
that uses the same gspca-cpia sub-driver.

What: Video4Linux obsolete drivers using V4L1 API
When: kernel 2.6.38
Files: drivers/staging/cpia/*
Check: drivers/staging/cpia/cpia.c
Why: There are some drivers still using V4L1 API, despite all efforts we've done
to migrate. Those drivers are for obsolete hardware that the old maintainer
didn't care (or not have the hardware anymore), and that no other developer
could find any hardware to buy. They probably have no practical usage today,
and people with such old hardware could probably keep using an older version
of the kernel. Those drivers will be moved to staging on 2.6.37 and, if nobody
care enough to port and test them with V4L2 API, they'll be removed on 2.6.38.
