drm/ast: Disconnect BMC if physical connector is connected

commit 8d6ef26501b97243ee6c16b8187c5b38cb69b77d upstream.

Many user-space compositors fail with mode setting if a CRTC has
more than one connected connector. This is the case with the BMC
on Aspeed systems. Work around this problem by setting the BMC's
connector status to disconnected when the physical connector has
a display attached. This way compositors will only see one connected
connector at a time; either the physical one or the BMC.

drm/ast: report connection status on Display Port.

Aspeed always report the display port as "connected", because it
doesn't set a .detect_ctx callback.
Fix this by providing the proper detect callback for astdp and dp501.

This also fixes the following regression:
Since commit fae7d186403e ("drm/probe-helper: Default to 640x480 if no
EDID on DP") The default resolution is now 640x480 when no monitor is
connected. But Aspeed graphics is mostly used in servers, where no monitor
is attached. This also affects the remote BMC resolution to 640x480, which
is inconvenient, and breaks the anaconda installer.

v2: Add .detect callback to the dp/dp501 connector (Jani Nikula)
v3: Use .detect_ctx callback, and refactors (Thomas Zimmermann)
Add a BMC virtual connector
v4: Better indent detect_ctx() functions (Thomas Zimmermann)
v5: Enable polling of the dp and dp501 connector status
(Thomas Zimmermann)
v6: Change check order in ast_astdp_is_connected (Jammy Huang)

Most aspeed devices have a BMC, which allows to remotely see the screen.
Also in the common use case, those servers don't have a display connected.
So add a Virtual connector, to reflect that even if no display is

drm/ast: Distinguish among chip generations

ASpeed distinguishes among various generations of the AST graphics
chipset with various models. [1] The most-recent model AST 2600 is
of the 7th generation, the AST 2500 is of the 6th generation, and so
on.

The ast driver simply picks one of the models as representative for
the whole generation. In several places, individual models of the
same generation need to be handled differently, which then requires
additional code for detecting the model.

Introduce different generations of the Aspeed chipset. In the source
code, refer to the generation instead of the representation model where
possible. The few places that require per-model handling are now clearly
marked.

In the enum ast_chip, we arrange each model's value such that it
encodes the generation. This allows for an easy test. The actual values
are ordered, but not of interest to the driver.
