riscv: disable HAVE_LD_DEAD_CODE_DATA_ELIMINATION for LLD
Linking allyesconfig with ld.lld-17 with CONFIG_DEAD_CODE_ELIMINATION=y takes hours. Assuming this is a performance regression that can be fixed, tentatively disable this for now so that allyesconfig builds don't start timing out. If and when there's a fix to ld.lld, this can be converted to a version check instead so that users of older but still supported versions of ld.lld don't hurt themselves by enabling CONFIG_LD_DEAD_CODE_DATA_ELIMINATION=y.
