The Versatile CLCD helpers call dma_alloc_writecombine() which is only available on ARM and AVR32, meaning they won't build on other platforms including arm64. Unfortunately the current Kconfig enables the symbol by default if ARCH_VEXPRESS is defined which means that it is enabled on arm64 when building for the ARM reference platforms and models for ARMv8 since they have many hardware similarities with their pre-ARMv8 systems.
Since all the systems that need the helpers are ARM systems fix this by adding a dependency on ARM.
