ARM: 6904/1: MTD: Add integrator-flash feature to physmap

In the process of moving platforms away from integrator-flash
(aka armflash), add to physmap the few features that make
armflash unique:

- optionnal probing for the AFS partition type
- init() and exit() methods, used by Integrator to control
  write access to the various onboard programmable components
