This patch adds common elements for ck804-based boards.

changes by file:
src/northbridge/amd/amdk8/northbridge.c:
	Add high tables code ala Stefan's code for the i945.

src/southbridge/nvidia/ck804/ck804_lpc.c:
	Enable High Precision Event Timers.
	Add pm_base for ACPI.

src/southbridge/nvidia/ck804/ck804_fadt.c:
	Since fadt is only dependent on the Southbridge, add it here.

src/southbridge/nvidia/ck804/Config.lb:
	Compile in ck804_fadt.c
