[PATCH 1/2] acpi: acpi_table: Fix compilation on QFW enabled platforms

[Patrick Rudolph <patrick.rudolph@9elements.com>]

On ACPI enabled platforms where QFW passes in the pre-generated
ACPI tables do not attempt to fill MADT and FADT. On all other
platforms MADT and FADT must be filled by SoC or mainboard code.

Fixes a compilation error on QEMU platforms that enable:
- CONFIG_QFW_ACPI
