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.

          Choose this if you have a NXP i.MX8MQ based system and want to use the
          Display Controller Subsystem. This option enables DCSS support.
