acrn-config: re-generate TTYS_INFO in native board

Browse Source 
Currently, MMIO PCI BDF of ttyS was indexed by IRQ, but it may found
the wrong BDF when the IRQ was shared and it is not expected. So, the
patch uses the MMIO base to query /proc/iomem to find BDF, the waring
will get if BDF is not present in iomem.
