With the dependency being _in_ acpi_boot_init(), the invocation of
acpi_mmcfg_init() should now be moved there.
Yes, I feel better to move pt_pci_init() and acpi_mmcfg_init() in
acpi_boot_init() before acpi_mmcfg_init(). Any more comments?
I see acpi_boot_init() is empty func when CONFIG_ACPI_BOOT isn't set. Do
we support disabling this config option? If yes, I think above change
will break non-acpi case.
Thanks
