gma: Reverse meaning of GTT_Rotation_Offset

We used to add the second mapping for a 90 degree rotated frame-
buffer at `FB.Offset + GTT_Rotation_Offset` and patched the offset
when configuring the pipe. Instead, we expect the final offset in
`FB.Offset` (which should include `GTT_Rotation_Offset` when using
the default framebuffer setup.
