V4L/DVB (11305): cx88: prevent probing rtc and ir devices

tuner-core.c contains a hack for cx88 board to prevent probing of certain
addresses:

        /* HACK: Ignore 0x6b and 0x6f on cx88 boards.
         * FusionHDTV5 RT Gold has an ir receiver at 0x6b
         * and an RTC at 0x6f which can get corrupted if probed.
         */

With the new i2c API this hack no longer works. So instead change the
list of tuner probe addresses in the cx88 driver itself, which is much
more clean.
