auxdisplay/ht16k33: Use struct fb_info.screen_buffer
Use info->screen_buffer when reading and writing framebuffers in system memory. It's the correct pointer for this address space. The struct fb_info has a union to store the framebuffer memory. This can either be info->screen_base if the framebuffer is stored in I/O memory, or info->screen_buffer if the framebuffer is stored in system memory. As the driver operates on the latter address space, it is wrong to use .screen_base and .screen_buffer must be used instead. This also gets rid of casting needed due to not using the correct data type.
