[media] staging: add MEDIA_SUPPORT dependency
staging media drivers tend to have a build time dependency on the media support. In particular, the newly added pulse8 cec driver can only be a loadable module if MEDIA_SUPPORT=m, but its build dependency is on a 'bool' symbol (MEDIA_CEC), so a randconfig build can fail with pulse8_cec built-in: drivers/staging/built-in.o: In function `pulse8_disconnect': dgnc_utils.c:(.text+0x114): undefined reference to `cec_unregister_adapter' drivers/staging/built-in.o: In function `pulse8_irq_work_handler': dgnc_utils.c:(.text+0x1bc): undefined reference to `cec_transmit_done' dgnc_utils.c:(.text+0x1d8): undefined reference to `cec_received_msg' dgnc_utils.c:(.text+0x1f4): undefined reference to `cec_transmit_done' dgnc_utils.c:(.text+0x218): undefined reference to `cec_transmit_done' dgnc_utils.c:(.text+0x23c): undefined reference to `cec_transmit_done' drivers/staging/built-in.o: In function `pulse8_connect': dgnc_utils.c:(.text+0x844): undefined reference to `cec_allocate_adapter' dgnc_utils.c:(.text+0x8a4): undefined reference to `cec_delete_adapter' dgnc_utils.c:(.text+0xa10): undefined reference to `cec_register_adapter' Originally, MEDIA_CEC itself was a tristate symbol, which would have prevented this, but since 5bb2399a4fe4 ("[media] cec: fix Kconfig dependency problems"), it doesn't work like that any more. This encloses all of the staging media drivers in a CONFIG_MEDIA_SUPPORT dependency in Kconfig, which solves the problem by enforcing that none of the drivers can be built-in if the media core is a module.
