[PATCH] atyfb: Fix hardware cursor handling
Fix image and color handling in atyfb_cursor()
- In the 2-bit scheme of the cursor image, just set the first bit to be
always zero (turn off transparency and/or XOR), and just do the masking
manually
- The cursor color is converted into 32-bit RGBA8888 using struct fb_cmap.
Each component in the cmap is u16 in size, so mask the upper 8 bits.
