The ADF_GENERAL_SEC configuration section contains values that must be preserved during state transitions (down -> up, up -> down). This patch modifies the logic in adf_dev_shutdown() to maintain all key values within this section, rather than selectively saving and restoring only the ADF_SERVICES_ENABLED attribute. To achieve this, a new function has been introduced that deletes all configuration sections except for the one specified by name. This function is invoked during adf_dev_down(), with ADF_GENERAL_SEC as the argument. Consequently, the adf_dev_shutdown_cache_cfg() function has been removed as it is now redundant. Additionally, this patch eliminates the cache_config parameter from the adf_dev_down() function since ADF_GENERAL_SEC should always be retained. This change does not cause any side effects because all entries in the key-value store are cleared when a module is unloaded.
