The BMC output can be viewed via the BMC's web interface or a
similar client. Represent it as virtual encoder and connector.
It's attached to the same CRTC as the VGA connector.
The connector's status depends on the physical connector's status.
The BMC is only connected if the physical connector is not. This
is necessary to support userspace clients that can only handle a
single output per CRTC.
The BMC is a server feature. Add a BMC output for all server chips,
but not the desktop models.

Move the PIXPLLC code into per-model source files and wire it up
with per-model callbacks. No functional changes.
The PIXPLLC pixel-clock is part of the CRTC, but really separate
hardware that varies with each model of the G200. Move the PIXPLLC
code for each model into the per-model source file and call it from
CRTC helpers via device functions.
This allows to remove struct mgag200_pll and the related code. The
new callbacks behave like the CRTC's atomic_check and atomic_enable
functions.

Provide an init function for each model's DAC registers. Remove
the shared helper.
The code for initializing the DAC registers consisted of a large
table of default value, plus many exceptions for the various G200
models. Providing a per-model implementation makes if more readable.
At some point, some of the initialization should probably move into
the modesetting code.

Rework mgag200_regs_init() and mgag200_mm_init() into device preinit
and init functions. The preinit function, mgag200_device_preinit(),
requests and maps a device's I/O and video memory. The init function,
mgag200_device_init() initializes the state of struct mga_device.
Splitting the initialization between the two functions is necessary
to perform per-model operations between the two calls, such as reading
the unique revision ID on G200SEs.
