SoC people may send many parameters to configure the drivers via kernel
command line. If COMMAND_LINE_SIZE is not enough, they may go through
unexpected error.
To avoid the potential pain, we had better increase COMMAND_LINE_SIZE.

Increase COMMAND_LINE_SIZE as the current default value is too low
for syzbot kernel command line.
There has been considerable discussion on this patch that has led to a
larger patch set removing COMMAND_LINE_SIZE from the uapi headers on all
ports. That's not quite done yet, but it's gotten far enough we're
confident this is not a uABI change so this is safe.
