Kyösti Mälkki 32d47eb688 soc/intel: Rename <intelblocks/chip.h>
The filename chip.h has a special purpose with the generation
of static devicetree, where the configuration structure name matches
the path to the chip.h file. For example, soc/intel/skylake/chip.h
defines struct soc_intel_skylake_config.

The renamed file did not follow this convention and the structure it
defines would conflict with one defined soc/intel/common/chip.h if such
is ever added.
