flash storage: move to flash + 0x70000 

This requires recompiling and flashing the runtime and the entire
storage area file system (ip address and idle kernel).

* with ppp the runtime is larger than 0x40000 now
* 0x60000 for the runtime should give enough space for a while,
  even including a fatter scheduler or runtime components
  in other languages
* for both pipistrello and kc705 this leaves the unused space
  starting at a nice round number
* the relevant flashes nowadays are 0x1000000 large
