They are correct.  The crtc blocks are repeated at different offsets within the
register aperture.  So if you wanted to access EVERGREEN_CRTC_CONTROL for crtc
0, you access: EVERGREEN_CRTC_CONTROL + EVERGREEN_CRTC0_REGISTER_OFFSET, for
crtc 1:
EVERGREEN_CRTC_CONTROL + EVERGREEN_CRTC1_REGISTER_OFFSET, etc.
