It matters because everything between 0x4100 - 0x4107 are Moorestown if you ask
the macro, but are assigned to oaktrail_chip_ops. That makes Oaktrail ==
Moorestown. IS_OAK might be a more appropriate name.

IS_MRST is primarily used for two things:
1) Take LVDS enable fuse value into account
2) Tell that LVDS must be on Pipe A

Those things where required for him to get the panel working,
so why not include the 0x4108 in the IS_MRST check?
