cpu_start chrashes when CONFIG_SECURE_FLASH_ENC_ENABLED and LOG_LEVEL>ERROR (IDFGH-2799)

[jas39]

call_start_cpu0 in cpu_start calls esp_efuse_api which uses ESP_LOG* instead of ESP_EARLY_LOG_*
at this point the ESP_LOG_* functionality is not initiated and causes a crash.

Using idf v4.0, compiling with default cmake toolchain and VSCode

Hi @jas39 !
Thanks for your report. I will fix this on the master and will backport to the previous version as well.
