With a microvm-only build based on a custom device config,
we get a link failure due to undefined reference to
build_pci_host_bridge_osc_method() which is defined in hw/acpi/pci.c and
whose compilation depends on CONFIG_ACPI_PCI. Although CONFIG_ACPI
and CONFIG_PCI are set with such configuration, implied CONFIG_ACPI_PCI
in config PCI_EXPRESS_GENERIC_BRIDGE is not selected as expected.
It Looks like CONFIG_ACPI_PCI must be enforced and this patch selects
CONFIG_ACPI_PCI in MICROVM config directly as done for PC config.
