When QuickConnect is enabled in SetConfig request with the remanent data being unavail/deleted, then the EN PHY config is not set as expected

When I delete the remanent data, then send a SetConfig packet with bQuickConnectFlags = 0x3, and issue a channel init or actual power cycle, I expect QuickConnect to be enabled (which is observable by actual Quick Connecting with the next power cycle or channel init). In this case, it is also expected that EN attributes 6 and 768 are set to fixed values.

This is not the case unless the device actually has remanent data. However, since remanent data is not written to flash unless the runtime configuration changes for the first time, we do not st the EN attributes to fixed values with the current implementation.
