[media] dvb-usb-v2: Don't ask user to select Cypress firmware module

The dvb-usb-v2 cypress firmware module is not optional, as drivers
won't work without it. So, instead of opening a menu for the user to
manually select, let the drivers that need it to select, hiding this
option from the Kconfig menu.
