There is already an 'if DVB_USB' condition wrapping most config
options, making the 'depends on' statement for each a duplicate
dependency (dead code).

Additionally, we can move the 'if DVB_USB' condition up to include
the DVB_USB_DEBUG config option, and also remove its specific
'depends on' statement.

This dead code was found by kconfirm, a static analysis tool for Kconfig.
