lenovo/t400: Consolidate `acpi/platform.asl`

The ASL code is already present in
`southbridge/intel/common/acpi/platform.asl` and
`cpu/intel/common/acpi/cpu.asl`.

So include these files instead of duplicating the code.

Something similar was don in commit commit 24813c14 (i945: Consolidate
acpi/platform.asl).
