Subject: [Patch v4 0/3] Add new compatible for Exynos3250

Since MFC v7 support was added for Exynos5420 and Exynos3250
SoC with same compatible string "samsung,mfc-v7". As both SoCs
having different hardware properties and having same compatible
string for both SoCs doesn't seems to be correct.
Add a new compatible to differentiate the two SoC's MFC IP,
at the same time to keep git bisect happy, add a fallback to mfc-v7
for Exynos3250.

Changes since v3:
 - Addressed review comments from Krzysztof Kozlowski.
   - Added new compatible string for Exynos3250 followed by mfc-v7 fallback.

Changes since v2:
 - Addressed review comments from Krzysztof Kozlowski.
   - Changed subject prefixes matching the subsystem.

Changes since v1:
 - Addressed review comments from Marek Szyprowski.
   - Changed subject prefix from arm64 to arm.

 - Addressed review comments from Krzysztof Kozlowski.
   - Changed subject prefixes matching the subsystem.
   - Added new compatible string for Exynos3250 followed by mfc-v7 fallback.
   - Removed checkpatch warnings from s5p_mfc.c.Sent separate patch
     series for the same.
   
 - Addressed review comments from Tommaso Merciai.
   - Change in commit message body from used to use in Patch-2.
