fw: Remove use of timer in flash operations
Since we want to keep the user of the timer to the device apps, remove
the use of the timer for implementing a delay when writing to flash.
Let's try without any delay what so ever, just busylooping the query
to the chip.

fw: Add pre loaded flash app and flash data storage
- Add per app flash storage
  - Adds four data areas. An app can allocate an area. Once allocated
    the area is tied to the CDI of the app and can only be
    read/written/deallocated by the same app.
- Add two pre loaded app slots to flash
  - Load an app from the first slot at boot. The app digest must match a
    specific digest specified in firmware.
  - Optionally load an app from the second slot
- Add a resetinfo area in FW_RAM which is used to signal an app's intent
  of resetting the system and, optionally, pass data to firmware or the
  next app in a bootchain.
