acpi: don't fill FADT, MADT if CONFIG_QFW_ACPI=y

Browse source 
When using the ACPI tables supplied by QEMU, we don't need to build the
FADT and MADT tables in U-Boot.

This patch avoids a build failure

    make qemu-riscv64_smode_defconfig acpi.config

    riscv64-linux-gnu-ld.bfd: lib/acpi/acpi_table.o:
    in function `acpi_write_fadt':
    lib/acpi/acpi_table.c:265:(.text.acpi_write_fadt+0x15c):
    undefined reference to `acpi_fill_fadt'

    riscv64-linux-gnu-ld.bfd: lib/acpi/acpi_table.o:
    in function `acpi_write_madt':
    lib/acpi/acpi_table.c:294:(.text.acpi_write_madt+0x52):
    undefined reference to `acpi_fill_madt'
