* Storage: drop internal storage

* Storage: rollback some unnecessary changes

* Storage: rollback some unnecessary changes part 2

* Storage: do not return storage if it is not ready

* Save PIN code to RTC, update settings

* Simplify the code, clean up includes

* Rearrange some code

* apps: storage_move_to_sd: conditionally enable with --extra-define=STORAGE_INT_ON_LFS

* Load Desktop settings automatically

* Redirect /any to /ext

* Abolish storage_move_to_sd app

* Remove as many mentions of ANY_PATH as possible

* Fix desktop settings wrongly not loading
