This patch adds ACPI support for Tyan s2891, s2892, and s2895. There is still

a problem with IRQ 9, but besides that Linux is happy.  BSOD in Windows still.

changes by file:

src/mainboard/tyan/s289X/Options.lb:
	Add options and defaults for ACPI tables and resources.

src/mainboard/tyan/s289X/mainboard.c:
	Add high_tables resource ala Stefan's code for the Kontron.

src/mainboard/tyan/s289X/acpi_tables.c:
	Fill out the ACPI tables, using existing code where possible.
	Only the madt is different between the boards, to be combined later.

src/mainboard/tyan/s289X/Config.lb:
	Compile in acpi_tables.c and dsdt.dsl.
	Turn on the parallel port and the real-time-clock.

src/mainboard/tyan/s289x/dsdt.dsl:
	The board layout (thanks Rudolf) and interrupts from mptable.c

src/mainboard/tyan/s289x/mptable.c:
	Minor formatting changes to make them diff better.

src/superio/smsc/lpc47b397/superio.c:
	Correct the size of the real-time-clock so it can be where it belongs.
