[media] s5p-g2d: Add support for G2D H/W Rev.4.1

Browse Source 
Modified the G2D driver (which initially supported only H/W Rev.3)
to support H/W Rev.4.1 present on Exynos4x12 and Exynos52x0 SOCs.
- Set the SRC and DST type to 'memory' instead of using reset values.
- FIMG2D v4.1 H/W uses different logic for stretching(scaling).
- Use CACHECTL_REG only with FIMG2D v3.
