cpu/esp_comomon: rename cpu_conf.h to cpu_conf_common.h

To be able to define common configurations for all ESP CPUs, the CPU specific configuration cpu_conf.h has to include a common configuration. For that purpose cpu_conf.h in cpu/esp_common is renamed to cpu_conf_common.h and included in CPU specific configurations.
