Subject: [PATCH] drm/amd/display: Limit DCN to x86 arch
DCN bw calcs currently rely on the following gcc options:
-mhard-float -msse -mpreferred-stack-boundary=4
We probably shouldn't allow building this on architectures other than x86.

Tested this change by running make menuconfig and make modules with ARCH=arm.
