Analogous to ACPI's /sys/firmware/acpi/tables/...
create /sys/firmware/sfi/tables/
The tables are primariy for the kernel,
but sometimes it is useful for user-space to be
able to read them.

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.
