[PATCH v2 3/4] drm/gma500: Remove CONFIG_X86 conditionals from source files

[Thomas Zimmermann <tzimmermann@suse.de>]

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.
