[POWERPC] bootwrapper: serial_console_init() fixes
1. Search the entire compatible list for serial devices.
The serial code previously did a simple strcmp on the compatible
node; this fails when the match string is not the first compatible
listed. Use dt_is_compatible() instead.
2. Don't call serial_edit_cmdline if getc isn't defined.
