This is a variant patch from Rafael J. Wysocki's ACPI / init: Run acpi_early_init() before efi_enter_virtual_mode()
According to Matt Fleming, if acpi_early_init() was executed before efi_enter_virtual_mode(), the EFI initialization could benefit from it, so Rafael's patch makes that happen. And, we want accessing ACPI TAD device to set system clock, so move acpi_early_init() before timekeeping_init(). This final position is also before efi_enter_virtual_mode(). v2: Move acpi_early_init() before timekeeping_init() to prepare setting system clock with ACPI TAD. v1: Rafael J.
