ibft: Update iBFT handling for v1.03 of the spec.
- Use struct acpi_table_ibft instead of struct ibft_table_header
- Don't do reserve_ibft_region() on UEFI machines (section 1.4.3.1)
- If ibft_addr isn't initialized when ibft_init() is called, check for
ACPI-based tables.
- Fix compiler error when CONFIG_ACPI is not defined.
