soc: moved kconfig options out of the target component. Moved the following kconfig options out of the target component: * CONFIG_ESP_DEFAULT_CPU_FREQ -> esp_system * ESP_REV_MIN -> esp_hw_support ESP_TIME_SYSCALL -> newlib ESP_RTC_ -> esp_hw_support Where applicable these target specific konfig names were merged into a single common config, e.g; CONFIG_ESP*_DEFAULT_CPU_FREQ -> CONFIG_ESP_DEFAULT_CPU_FREQ_MHZ 2022-03-02 15:49:31 +08:00
