V4L/DVB (9037): Fix support for Hauppauge Nova-S SE
Different backends have different input busses (saa7146, flexcop).
To reflect that a config-option to the s5h1420-driver was added which makes
the output mode selectable.
Furthermore the s5h1420-driver is now doing the same i2c-method as it was done
before adding support for other i2c-users.
This patch needs to go into the current release of the kernel, as this driver
is currently broken.
(Thanks to Eberhard Kaltenhaeuser for helping out to debug this issue.)
