s390/sclp: Add VT220 support to early sclp console
When running under qemu with the default configuration (-nographic), there is only a VT220 SCLP console, no line-mode SCLP console. Add VT220 support to the early SCLP console so the user has a chance to see critical error messages during early boot. None of the existing users of _sclp_print_early() check the return code. Instead of trying to come up with return code semantics when printing to multiple consoles (any or all of which may fail), we just drop the return code entirely. Tested on z/VM (line mode console) and LPAR (VT220 and line mode console). Tested on qemu/KVM with VT220 console and / or line mode console.
