linux: Move xmknod{at} to compat symbols
It also decouple mknod{at} from xmknod{at}. The riscv32 ABI was added on 2.33, so it is safe to remove the old __xmknot{at} symbols and just provide the newer mknod{at} ones. Checked with a build for all affected ABIs. I also checked on x86_64, i686, powerpc, powerpc64le, sparcv9, sparc64, s390, and s390x. Reviewed-by: Lukasz Majewski <lukma@denx.de>
