Subject: [PATCH 7/7] video: fbdev: bt431: Correct cursor format control
 macro

The Bt431 cursor generator supports simultaneous generation of a 64 x 64
and a cross hair cursor in which the cursor format control bit (bit D4)
of the command register "specifies whether the contents of the cursor
RAM are to be logically exclusive-ORed (logical zero) or ORed (logical
one) with the cross hair cursor".  Rename the relevant macro accordingly.
