Change ACPI to use dev_archdata instead of firmware_data
This patch changes ACPI to use the new dev_archdata on i386, x86_64
and ia64 (is there any other arch using ACPI ?) to store it's
acpi_handle.
It also removes the firmware_data field from struct device as this
was the only user.
Only build-tested on x86
