drm/vc4: hdmi: Restore cec physical address on reconnect
[ Upstream commit 4d8602b8ec16f5721a4d1339c610a81f95df1856 ]
Currently we call cec_phys_addr_invalidate on a hotplug deassert.
That may be due to a TV power cycling, or an AVR being switched
on (and switching edid).
This makes CEC unusable since our controller wouldn't have a physical
address anymore.
Set it back up again on the hotplug assert.
