[PATCH] v4l: bttv driver update 

From: Gerd Knorr <kraxel@bytesex.org>

bttv driver update.  Changes:

(1) Added a new, sysfs-based interface to allow access to the bt878 gpio
    lines from other kernel modules (new bttv-gpio.c file), which fixes alot
    of problems the old interface has (which still is in bttv-if.c, to be
    removed in 2.7).

(2) moved the i2c code from bttv-if.c to bttv-i2c.c.

(3) created a new "struct bttv_core" and moved some of the entries from
    "struct bttv" to the new one.  This is needed for (1) and makes the patch
    pretty big, althrough there is no actual code changes.

(4) first cut for suspend support (S1 works for me).

(5) usual batch of new/updated tv card list entries.

(6) minor fixes.
