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.
