mb/emulation/qemu-i440fx: Add acpi_name handler for QEMU
QEMU does not have a separate northbridge chip, so the mainboard
needs to handle the ACPI name and paths so that devices can get
generated into the SSDT properly. This fixes the PIRQ and TPM
table generation.
This issue can be seen in the coreboot output:
ACPI_PIRQ_GEN: Missing LPCB ACPI path
