Extend SFI to access standard ACPI tables.
(eg. the PCI MCFG) using sfi_acpi_table_parse().

Note that this is _not_ a hybrid ACPI + SFI mode.
The platform boots in either ACPI mode or SFI mode.

SFI runs only with acpi_disabled=1, which can be set
at build-time via CONFIG_ACPI=n, or at boot time by
the failure to find ACPI platform support.

So this extension simply allows SFI-platforms to
re-use existing standard table formats that happen to
be defined to live in ACPI envelopes.

drivers/sfi/sfi_core.c contains the generic SFI implementation.
It has a private header, sfi_core.h, for its own use and the
private use of future files in drivers/sfi/

CONFIG_SFI=y enables the kernel to boot and run optimally
on platforms that support the Simple Firmware Interface.

Thanks to Jacob Pan for prototyping the initial Linux SFI support,
and to Feng Tang for Linux bring-up and debug both in emulation
and on Moorestown hardware.

See http://simplefirmware.org for more information on SFI.
