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.
