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.
