When compiling for 32bit platforms, the compilation fails with:

This patch adds a dependency on ARM64 since no 32bit SoCs have DCSS, so far.
Usual way to fix this correctly is using the right division macros, not limiting the driver to 64bit. But this works for now, would be good to fix this properly for compile-testing and all that.
I didn't see the point in using the macros since this is running only on 64bit. Though I will probably revisit it and fix it properly in a subsequent patch.

Please push to drm-misc-next.
About that, I may need some help pushing it.
I've already pushed a few minutes ago, so we don't disturb the build tests any longer.
