sde: resource config: rectangle alignment for video and rotator

1. Align rectangle to be even for video format input.
2. Align width and height for rotator downscaling case.
3. Validate scaling again after config is done because scaling ratio
might be changed.
4. Make sure layer count doesn't exceed mixer stage number.
5. Add sde.disable_rotator_downscaling property for disabling
rotator downscaling.
6. Add sde.disable_decimation property for disabling decimation
7. Disable 2 pipes on non-display_split case temporarily as z-order
needs be different
