V4L/DVB (12684): DVB: make DVB_MAX_ADAPTERS configurable 



Support for more than 8 DVB devices is requested regularly so make it
a kconfig variable instead of a header define. Values in the range 4-32
are tested.

	  Maximum number of DVB/ATSC adapters. Increasing this number

	  increases the memory consumption of the DVB subsystem even

	  if a much lower number of DVB/ATSC adapters is present.

	  Only values in the range 4-32 are tested.



	  If you are unsure about this, use the default value 8
