This patch implements a simple interface between the EC and mainboard
ASL code. This interface does not rely on the preprocessor, and
prevents name conflicts by scoping the interface methods. As this
interface is documented on the coreboot wiki, an in-tree documentation
is not provided.

This is handled by generating an SMI when GEVENT22 goes low. This pin
is driven by the EC when the lid opens or closes. This SMI is
disabled when switching to ACPI mode, so ACPI OSes are not affected.

Refactor hudson_enable_gevent_smi() to allow configuring the interrupt

a separate file that is included in both ramstage and SMM. This is
useful for SMI handlers which need to enable or disable GEVENT SMIs
on-the-fly. A follow-up patch makes use of this infrastructure.

Intercept the low battery SMI from the EC, and shut down the system
immediately. The EC only sends this SMI when the OS did not enable
ACPI mode, so ACPI OSes are not affected by this.
On the other hand, payloads such as GRUB or SeaBIOS will experience
the shutdown. This behavior is helpful for protecting the battery, for
example, when the OS fails to boot and we are stuck in the payload.
The low battery SMI is triggered at 10% charge, at which point the risk
of cell degradation exists.

The EC may disable some functionality, such as Caps Lock LED and
battery charging if it never receives a command to go in APM mode. If
we start it in APM mode, then immediately switch to ACPI mode, it will
not get its SCIs serviced until an ACPI OS boots. If its SCIs are not
serviced, it may assume the OS has hung.
The way we solve this is to initalize the EC in APM mode, and only
switch it to ACPI when an ACPI-capable OS issues the ACPI_ENABLE
command. The switch has to be handled in SMM.
Although we aren't yet processing SMIs from the EC, we are reading the
status in order to satisfy the EC that the event is handled.

This sets up the infrastructure to handle SMIs generated by the Hudson
southbridge. An API for interfacing to mainboard handlers is not
defined at this point. A few functions are defined to allow mainboard
code to enable SMIs from GEVENT pins. These are the only functions which
I expect to be needed anytime in the foreseeable future.
SMIs are always acknowledged and cleared, as not clearing an SMI will
cause us to re-enter the SMI, effectively bricking the machine if a
southbridge-generated SMI without a handler occurs.

Since AGESA is stage-independent, we can build it just once, and use

We still keep the practice of specifying every single AGESA directory
as an include dir and adding the AGESA CFLAGS to our global CFLAGS;
this is needed due to the way AGESA builds.
