John Baldwin e6c8bc291a Rework the DSDT generation code a bit to generate more accurate info about
LPC devices.  Among other things, the LPC serial ports now appear as
ACPI devices.
- Move the info for the top-level PCI bus into the PCI emulation code and
  add ResourceProducer entries for the memory ranges decoded by the bus
  for memory BARs.
- Add a framework to allow each PCI emulation driver to optionally write
  an entry into the DSDT under the \_SB_.PCI0 namespace.  The LPC driver
  uses this to write a node for the LPC bus (\_SB_.PCI0.ISA).
- Add a linker set to allow any LPC devices to write entries into the
  DSDT below the LPC node.
- Move the existing DSDT block for the RTC to the RTC driver.
- Add DSDT nodes for the AT PIC, the 8254 ISA timer, and the LPC UART
  devices.
- Add a "SuperIO" device under the LPC node to claim "system resources"
  aling with a linker set to allow various drivers to add IO or memory
  ranges that should be claimed as a system resource.
- Add system resource entries for the extended RTC IO range, the registers
  used for ACPI power management, the ELCR, PCI interrupt routing register,
  and post data register.
- Add various helper routines for generating DSDT entries.
