Move calls to stop and start BMC scanout from CRTC helpers to the
VGA-BMC encoder's atomic_disable and atomic_enable. Makes the BMC
scanout transparent to the CRTC.

DRM's atomic helpers call an encoder's atomic_disable and atomic_enable
helpers for all enabled encoders. The BMC stops scanning out the VGA
signal if modeset disables the VGA encoder, and starts scanning out
if the modeset enables the VGA encoder.

Control the VIDRST pin from the VGA-BMC encoder's atomic_check and
remove the respective code from CRTC. Makes the VIDRST functionality
fully composable.

The VIDRST pin allows an external clock source to control the SYNC
signals of the Matrox chip. The functionality is part of the CRTC,
but depends on the presence of the clock source. This is the case for
some BMCs, so control the pin from the VGA-BMC output.

The VGA-BMC connector selects the VGA output if a display has been
attached to the physical connector. Otherwise it selects the BMC
output. In any case, the connector status is set to 'detected', so
that the userspace compositor displays to it.

Depending on the setting, the connector's display modes either come
from the VGA monitor's EDID or from an internal list of BMC-compatible
modes.

The place for link training is in the encoder's atomic_enable
helper. Remove all related tests from other helper ASTDP functions;
especially ast_astdp_is_connected(), which tests HPD status.

DP link training is controlled by the firmware. A status flag reports
success or failure. The process can be fragile on Aspeed hardware. Moving
the test from connector detection to the atomic_enable allows for several
