drm/gma500: Remove CONFIG_X86 conditionals from source files
Remove the CONFIG_X86 conditionals from the source code. The driver already depends on X86 in the Kconfig file. Also, no one has been trying to build it on a non-x86 platform recently, or they would have noticed that drm_ttm_cache_flush() doesn't exist.
