The idea is just to have one function. Whichever prints the
string and panics the machine. If 'panic' does this properly
(and properly meaning it actually prints data when using
the earlyprintk=xen as well as console=hvc0) printout system
the we cuold just use 'panic' and not worry about it.

But if it does not, then we (and by we I mean you) should 
provide a variant of panic() that prints the data properly using the 
earlprintk mechanism. Preferrabily to make it generic.
