acpi/acpi.c: Split of ACPI table generation into separate files
acpi.c contains architectural specific things like IOAPIC, legacy IRQ, DMAR, HPET, ... all which require the presence of architectural headers. Instead of littering the code with #if ENV_X86 move the functions to different compilation units.
