init: Suppress wrong warning for bootconfig cmdline parameter
Since the 'bootconfig' command line parameter is handled before
parsing the command line, it doesn't use early_param(). But in
this case, kernel shows a wrong warning message about it.
[ 0.013714] Kernel command line: ro console=ttyS0 bootconfig console=tty0
[ 0.013741] Unknown command line parameters: bootconfig
To suppress this message, add a dummy handler for 'bootconfig'.
