nrf: mpconfigport: subtract config size from firmware size

Browse Source 
The BLE Config area needs to be subtracted from the size of the firmware.
THis is because the firmware is counted by walking backwards from the end
of memory, and the BLE config area is placed lower in memory than the
firmware.  Subtracting the BLE config size ensures the internal flash
filesystem doesn't try to use the firmware as storage.
