[PATCH] drm/imx/dcss: fix compilation issue on 32bit

[Laurentiu Palcu]

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

ERROR: modpost: "__aeabi_ldivmod"
[drivers/gpu/drm/imx/dcss/imx-dcss.ko] undefined!
ERROR: modpost: "__aeabi_uldivmod"
[drivers/gpu/drm/imx/dcss/imx-dcss.ko] undefined!

This patch adds a dependency on ARM64 since no 32bit SoCs have DCSS, so far.
