southbridge/hudson: Add support for ACPI enable/disable via SMI

This enables the ACPI SMI command port in the FADT table, and sets up
the hardware accordingly. If we have SMI enabled, then we don't set
the SCI_EN bit at boot, causing the OS to send the ACPI_ENABLE
command, as required by the ACPI spec. This gives us a chance to hook
into the mainboard_smi_apmc() handler.

hp/pavilion_m6_1035dx: Add SMI handler and handle EC requests

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 causes coreboot to call the keyboard initialization code for the

keyboard.

usbdebug: Reduce bus reset delays

According to EHCI specification, host controller software stops
the USB Reset condition by writing PORT_RESET=0. Software then
poll-waits this bit until controller hardware has completed USB
Reset sequence and read returns with PORT_RESET==0.

vendorcode/amd/agesa/fam15tn: Clean #includes in public headers

Right now, coreboot code using AGESA headers can only build if all the
AGESA path are given to the compiler via the "-I" option. This is sub-
optimal, as it requires us to have every AGESA source directory
specified as a compiler include path. This pollutes our global include
paths.

We restrict the compiler include paths to only allow "AGESA_ROOT/" and
"AGESA_ROOT/Include". We then modify the AGESA headers to specify
non-local include files relative to "AGESA_ROOT/Include".

We use the convention that includes relative to the directory of the
header are included as "path/to/header.h", while includes relative to
AGESA_ROOT are included as <path/to/header.h>.

This change allows building coreboot code based on AGESA with the
limited subset of include paths, but does not allow AGESA itself to
build with this restricted subset.

console: Drop driver list in ramstage

This framework was only available in ramstage. So we had to define
console output functions separately for bootblock, romstage and SMM.
Follow-up patches will re-enable all the consoles removed here,
in a more flexible fashion, and with less lines-of-code and copy-paste.

Also the driver list is not in a well-defined order and some of the
loops could exit without visiting all drivers.

NOTE: This build has no console in ramstage.
