global: Move remaining CONFIG_SYS_* to CFG_SYS_* The rest of the unmigrated CONFIG symbols in the CONFIG_SYS namespace do not easily transition to Kconfig. In many cases they likely should come from the device tree instead. Move these out of CONFIG namespace and in to CFG namespace.

video: exynos_fimd: Add framework to disable FIMD sysmmu On Exynos5420 and newer versions, the FIMD sysmmus are in "on state" by default. We have to disable them in order to make FIMD DMA work. This patch adds the required framework to exynos_fimd driver, and disables FIMD sysmmu on Exynos5420.

samsung,disable-sysmmu: Define this if you want to disable FIMD sysmmu.
(needed for Exynos5420 and newer versions)
Add the required FIMD sysmmu nodes to be
disabled with compatible string
