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.
