Change zigpy-cc to "legacy" and also list CC253x under zigpy-znp

Change zigpy-cc to be listed as "legacy" and also list CC253x devices under zigpy-znp as @puddly posted in home-assistant/home-assistant.io#17089 that all Texas Instruments Zugbee coordinators with any Z-Stack version are now relatively stable with zigpy-znp so should no longer be any no need to list versions.
