- Add config flag for boards that have their own fadt.c

This should eventually go, as fadt seems to be better
  put into the southbridge
- Add config flag for boards that have get_bus_conf.c
  Might be cleaned out as well, no idea
- Use flags where appropriate.
- Move the following rules to src/arch/i386/Makefile.inc:
  - fadt.o
  - dsdt.o
  - acpi_tables.o
  - get_bus_conf.o
- Rename objs_dsl_template in toplevel Makefile to the more
  appropriate objs_asl_template
- Remove all Makefiles that are empty now, which includes
  src/mainboard/Makefile.k8_CAR.inc and
  src/mainboard/Makefile.k8_ck804.inc
  and the include statements that used these files.
- Add workaround to intel/xe7501devkit:
  It uses ACPI in an unusual way: It adds a MADT, but no
  DSDT. As this is highly unusual, I didn't want to add
  explicit support for that scenario (and encourage such
  uses that way), and added a dummy dsdt.asl instead. It
  will be linked to dsdt.o, but not linked into the final
  binary.
