Sachin Kamat 479dda2218 ARM: EXYNOS: Fix NULL pointer dereference bug in Origen 
When DRM support for Samsung SoC and Samsung S3C framebuffer support
are selected, the kernel crashes as it does not get the required
platform data. Change the compile macro to CONFIG_DRM_EXYNOS_FIMD
to fix this.

Without this patch the following crash occurs during bootup:

Unable to handle kernel NULL pointer dereference at virtual address 00000000
PC is at 0x0
