* Outdated apps: add api-light-usage * Gpio: update SD card CS pin settings * API-power: added fns to disable/enable external 3v3 dc-dc * API-gpio: separated SD card detect routines * Resources: removed sd cs pin * SD card: low level init now resets card power supply * App SD-filesystem: use new card detect fns * SD card: fix low level init headers * SD card: more realilable low level init, power reset, exit from command read cycle conditionally * App SD-filesystem: led notifiers, init cycling * SD card: backport to F4 * SD card: handle eject in init sequence * SD card: api to set level on detect gpio * SPI: api to set state on bus pins * SD card: set low state on bus pins while power reset Co-authored-by: coreglitch <mail@s3f.ru>
