media: make RADIO_ADAPTERS tristate

Fix build errors when RADIO_TEA575X=y, VIDEO_BT848=m, and VIDEO_DEV=m.

The build errors occur due to [in drivers/media/Makefile]:
obj-$(CONFIG_VIDEO_DEV) += radio/
so the (would be) builtin tea575x.o is not being built.

This is also due to drivers/media/radio/Kconfig declaring a bool
Kconfig symbol (RADIO_ADAPTERS) that depends on a tristate (VIDEO_DEV),
so when VIDEO_DEV=m, RADIO_ADAPTERS becomes =y, and then the drivers
that depend on RADIO_ADPATERS can be configured as builtin (=y) or
as loadable modules (=m).

Fix this by converting RADIO_ADAPTERS to a tristate symbol instead
of a bool symbol.

Fixes these build errors:
