drm/mgag200: Store maximum resolution and memory bandwidth in device info
The maximum resolution and memory bandwidth are model-specific limits.
Both are used during display-mode validation. Store the values in struct
mgag200_device_info and simplify the validation code.
v2:
* 'bandwith' -> 'bandwidth' in commit message
