Do not keep the obsolete EDID around after unplugging the display
from the connector.

Permanently set the connector status to 'connected'. Return BMC modes
for connector if no display is attached to the physical DP connector.
Otherwise use EDID modes as before.
If the status of the physical connector changes, the driver still
generates a hotplug event. DRM clients will then reconfigure their
output to a mode appropriate for either physical display or BMC.
v3:
- use struct ast_connector.physical_status to handle BMC

Add struct ast_connector to track a connector's physical status. With
the upcoming BMC support, the physical status can be different from the
reported status.

Move the modesetting code for the various transmitter chips into
their own source files before adding BMC support. No functional
changes.
