ACPI/init: Invoke early ACPI initialization earlier
acpi_early_init() unmaps the temporary ACPI Table mappings which are used in the early startup code and prepares for permanent table mappings. Before the consolidation of the x86 APIC setup code the invocation of acpi_early_init() happened before the interrupt remapping unit was initialized. With the rework the remapping unit initialization moved in front of acpi_early_init() which causes an ACPI warning when the ACPI root tables get reallocated afterwards. Invoke acpi_early_init() before late_time_init() which is before the access to the DMAR tables happens.
