John Baldwin d95e7f5a7a Extract the code to find and map the MADT ACPI table during early kernel
startup and genericize it so it can be reused to map other tables as well:
- Add a routine to walk a list of ACPI subtables such as those used in the
  APIC and SRAT tables in the MI acpi(4) driver.
- Move the routines for mapping and unmapping an ACPI table as well as
  mapping the RSDT or XSDT and searching for a table with a given signature
  out into acpica_machdep.c for both amd64 and i386.
