SD card v7 BSP (#361)

Browse Source 
* Outdated apps: add api-light-usage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
