ps3fb: fix possible overlap of GPU command buffer and frame buffer
ps3fb: In the case of non-fullscreen video modes, there was a partial overlap
of the GPU command buffer and the frame buffer. Fix and cleanup various issues
with overlap and alignment:
- Move the GPU command buffer from the beginning to the end of video memory
- Exclude the GPU command buffer from the actual frame buffer memory
- Align the start of the virtual frame buffer to PAGE_SIZE instead of to 64
KiB, and don't waste memory if it's already aligned (for fullscreen modes)
- Take into account the alignment when checking memory requirements and
maximum number of frames
- Make sure fb_fix_screeninfo.smem_start always points to the virtual frame
buffer start, so we don't have to compensate for that in ps3fb_mmap()
