Move acpi_mmcfg_init() call in acpi_boot_init() before calling
acpi_parse_dmar()

pci_conf_read8() needs pci mmcfg mapping to work on multiple pci
segments system such as HPE Superdome-Flex.
Move acpi_mmcfg_init() call in acpi_boot_init() before calling
acpi_parse_dmar() so that when pci_conf_read8() is called in
acpi_parse_dev_scope(), we already have the mapping set up.
