sb/intel/i82371eb: Rework ACPI tables

Rework ACPI tables based on a mix of previous work on asus/p2b,
other boards in tree with better ACPI support, and OEM BIOS.
To be pulled in by DSDTs of mainboards using this southbridge.

Disable on-the-fly generation of mainboard _CRS node. It is not working
as it should and causes runtime errors when booting Linux. This node
to be included in mainboard DSDTs in followup patches.
