hp/dl145_g1: Adding ACPI support

Basic ACPI support for this old platform. Created by copying and
tweaking similar motherboard ACPI implementations in coreboot.
Works reasonably well under Linux, providing HPET-timers
and more under linux (tested under OpenSUSE 12.2 kernel 3.4.63-2.44).
Not tested under Windows.
