V4L/DVB (5955): Add support for DiB7070-based devices

This changeset adds support for DiB7070P-based devices by adding the
dib0070-driver and putting the appropriate layouts into
dib0700_devices.c

It also includes a new firmware for the dib0700 which is necessary to
make the DiB7070-boards work and it also should fix the i2c-problems
on some boards.
