Prepare hardlockup_panic_setup() to handle a comma-separated list of
options. Thus, it can continue parsing its own command-line options while
ignoring paremeters that are relevant only to specific implementations of
the hardlockup detector. Such implementations may use an early_param to
parse their own options.
