staging: sm750: Fix lynxfb_ops_imageblit() if image->depth != 1

Browse source 
If image->depth != 1, lynxfb_ops_imageblit() should fallback to call
cfb_imageblit(), not return directly. Otherwise it can't display the
boot logo.

- lots of checkpatch cleanup

- refine the code and remove unused code
- Implement hardware acceleration for imageblit if image->depth > 1
- check on hardware effects of removal of USE_HW_I2C and USE_DVICHIP (these two
