On arm32, the configuration options to specify the kernel command line type depend on ATAGS. However, the actual CMDLINE cofiguration option does not depend on ATAGS, and the code that handles this is not specific to ATAGS (see drivers/of/fdt.c:early_init_dt_scan_chosen()). Hence users who desire to override the kernel command line on arm32 must enable support for ATAGS, even on a pure-DT system. Other architectures (arm64, loongarch, microblaze, nios2, powerpc, and riscv) do not impose such a restriction. Hence drop the dependency on ATAGS.
