Key Huawei LTE routers in hass.data by config entry rather than unique id (#85788)

Key routers in hass.data by config entry rather than unique id

There's no particular reason to key them by the unique id; the config
entry id is a stronger, always available guarantee, and a much more
common convention across the HA codebase.

At some point, we might conceivably support devices we can't find a
proper unique id for; this would work for that purpose as well.
