atimach64gx: Add missing WRITE_VALUE_AND_LOG.

Browse Source 
This commit fixes conflict resolution mistakes in the following commits:
"atimach64gx: Let crtc_update calculate fb_ptr."
"atimach64gx: Redraw only when necessary."

"atimach64gx: Log unhandled overlay registers." was mistakenly included in "atimach64gx: Let crtc_update calculate fb_ptr.". The OVR_ registers were included because they may be needed for 2D acceleration in System 7.5.3 and later.
