V4L/DVB (4457): Remove dib3000-common-module
removing the dib3000-common-module. The common stuff is not common anymore - it will be only used by the 3000mb-driver. A new 3000mc/p-driver will be added which will share common stuff with dib7000. Signed-off-by: Patrick Boettcher <pb@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
