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.)
