drm/vc4: hdmi: make CEC adapter name unique

Browse Source 
[ Upstream commit 51128c3f2a7c98055ea1d27e34910dc10977f618 ]

The bcm2711 has two HDMI outputs, each with their own CEC adapter.
The CEC adapter name has to be unique, but it is currently
hardcoded to "vc4" for both outputs. Change this to use the card_name
from the variant information in order to make the adapter name unique.
