[PATCH] dvb: av7110 driver splitup 

From: Michael Hunold <hunold@linuxtv.org>

- after the firmware removal, split av7110.c into separate modules:

  - av7110.c: initialization and demux stuff

  - av7110_hw.c: lowlevel hardware access and firmware interface

  - av7110_ca.c: CI and ECD

  - av7110_av.c: audio/video MPEG decoder and remuxing stuff

  - av7110_v4l.c: v4l interface

- av7110 fixes that were notcies during splitup

  - rename some non-static functions to enhance readability

  - lots of coding style & whitespace fixes

  - return -ERESTARTSYS from ci_ll_read/write() if interrupted

  - use time_after() for timeouts

  - added some comments about firmware interface

  - removed some unused fields from struct av7110, retabbing

- follow driver splitup in Makefile
