i386: hvf: Fix smp boot hangs

Browse Source 
The machine that with hvf accelerator and smp sometimes boot hangs
because all processors are executing instructions at startup,
including early I/O emulations. We should just allow the bootstrap
processor to initialize the machine and then to wake up slave
processors by interrupt.
