soc/intel/xeon_sp: Add support for is_ioat_iio_stack_res
IOAT is the term for the on-chip accelerator technology of
Xeon-SP. In CPX and SPR, IOAT stack is also named as DINO stack.
Different SoC has different check criteria for IOAT stacks,
this patch introduces an util function to abstract these differences
as well as cleaning up the usage of names.
