Following current best practice, the instance of struct drm_device is now
embedded in struct mga_device. The respective field has been renamed from
'dev' to 'base' to reflect the relationship. Conversion from DRM device is
done via upcast. Using dev_private is no longer possible.
The patch also open-codes drm_dev_alloc() and DRM device initialization
is now performed by a call to drm_device_init().

The VRAM setup in mgag200_drv.c is part of memory management and
should be done in the same place. Merge the code into the memory
management's init function.

The MM setup code on mgag200 reads PCI BAR 0's start and length
several times. Reusing these values makes the code more readable.

The mgag200 driver does not use TTM any longer. Rename the related file
to mgag200_mm.c (as in 'memory management').
