MIPS: Fix CONFIG_OF_EARLY_FLATTREE=n builds
Configurations with CONFIG_OF_EARLY_FLATTREE=n fail to build since
commit
7784cac69735 ("MIPS: cmdline: Clean up boot_command_line
initialization") because of_scan_flat_dt() & of_scan_flat_dt() are not
defined in these configurations. Fix this by #ifdef'ing the affected
code...
