2013-11-25lynxpoint: Change SerialIO device enable reporting to ACPIDuncan Laurie
In order to report whether coreboot enabled a SerialIO device in ACPI mode we had been relying on reading NVS in the _STA method for the SerialIO device. The ACPI _STA method has restrictions on what it can access and is unable to access OperationRegions outside its scope which means it should not be trying to read NVS. This change adds a new SSDT to the ACPI tables and fills it with constants that indicate whether or not a device is enabled in ACPI mode. The ACPI code is changed to read these variables from the SSDT and use that instead of trying to query a variable in NVS. Attempt to use lpt-clk driver to probe the device clocks for SerialIO devices and see that the kernel does not complain about accessing the GNVS region.

2013-11-25lynxpoint: export mem console pointer in ACPIAaron Durbin
Instead of having an OS re-parse cbmem book-keeping records for the cbmem allocator just to get the console buffer export the pointer to the memory console directly in a field named 'CBMC'. This field lives in the GNVS table.

2013-11-24slippy: Clean up for easier portingDuncan Laurie
Minor tweaks to variable names in the slippy mainboard that make it easier to base a new board from without as much renaming. Also properly set up the thermal variables for the thermal zone that is defined in ACPI instead of using the generic setup from WTM2.
