media: dvb: fix DVB_MMAP dependency
Enabling CONFIG_DVB_MMAP without CONFIG_VIDEOBUF2_VMALLOC results in a link error: drivers/media/dvb-core/dvb_vb2.o: In function `_stop_streaming': dvb_vb2.c:(.text+0x894): undefined reference to `vb2_buffer_done' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_init': dvb_vb2.c:(.text+0xbec): undefined reference to `vb2_vmalloc_memops' dvb_vb2.c:(.text+0xc4c): undefined reference to `vb2_core_queue_init' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_release': dvb_vb2.c:(.text+0xe14): undefined reference to `vb2_core_queue_release' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_stream_on': dvb_vb2.c:(.text+0xeb8): undefined reference to `vb2_core_streamon' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_stream_off': dvb_vb2.c:(.text+0xfe8): undefined reference to `vb2_core_streamoff' drivers/media/dvb-core/dvb_vb2.o: In function `dvb_vb2_fill_buffer': dvb_vb2.c:(.text+0x13ec): undefined reference to `vb2_plane_vaddr' dvb_vb2.c:(.text+0x149c): undefined reference to `vb2_buffer_done' This adds a 'select' statement for it, plus a dependency that ensures that videobuf2 in turn works, as it in turn depends on VIDEO_V4L2 to link, and that must not be a module if videobuf2 is built-in.
