Subject: soc/amd/stoneyridge: remove LIDS field from global NVS

Since the LIDS field is only used in the ACPI code and not in the C code
of any mainboard using the Stoneyridge SoC, remove it form the global
NVS and add an ACPI object for this in the DSDT of the mainboards that
use it in their ACPI code. Eventually the LIDS object should probably be
moved to the EC's ACPI code, but that's out of scope for this patch.

TEST=google/liara doesn't show ACPI errors in Linux' dmesg
