drm/exynos: fimd: disable FIMD sysmmus

This patch adds a hack to explicitly disable the FIMD sysmmus
which will be ON by default during system bootup/resume.
This is needed when exynos IOMMU driver is not enabled.

This patch should be reverted when IOMMU driver is enabled.

Add the missing setting for DP CLKCON register.

This register is present on Exynos5 based FIMD controllers,
and needs to be set if we are using DP.
