sb,soc/intel: Apply transitional flag TCO_SPACE_NOT_YET_SPLIT
Tree is inconsistent with the use of TCO register space offsets and related preprocessor defines. The legacy space was offset from ACPI PM base by 0x60, but this changed with later platforms. The convenient way is to define the TCO registers relative to its base address and subtract 0x60 here, but this change cannot be easily done tree-wide or in one go. For the transient period, apply TCO_SPACE_NOT_YET_SPLIT flag until all platforms use a clean style of tco_{read,write} accessor functions instead of {read,write}_pmbase16(), or worse, inw/outl().
