Idan Horowitz 6348b63476 Kernel: Add kernelearlyputstr and use it in dbgln in very-early boot
This variant of dbgputstr does not lock the global log lock, as it is
called before the current or any other processor was initialized,
meaning that:
A) The $gs base was not setup yet, so we cannot enter into critical
   sections, and as a result we cannot use SpinLocks
B) No other processors may try to print at the same time anyway
