exynos3: fimc-is: Add support for FIMC IS on Exynos3250

The changes introduced provide support for FIMC-IS
subsystem avalilable on Exynos3250.
They cover the differences in both: the hardware itself
as well as the subtle discrepancies between the firmwares
controlling the FIMC IS on both SoCs.
Regarding the above mentioned firmware variations:
the initial driver has been extended with a simplified
interface handling those variations thus living the core
driver independent of the actual firmware version.
Missing code paths have been added to cover handling some of
the most probable failures/errors.
