introduce SIZE_DEFAULT and MMU_PAGESIZE_DEFAULT to make experiments with
...
smaller pagesize more versatile

implemented hook_interrupt() in PCI code
...
enabled PCI interrupts
ohci seems to damage something in PCI config -> PCI device enumeration
does not top with latest device
networking in EmuTOS lost (probably a result of PCI interrupt
implementation)
