core/flash: Use blocklevel accessors to load resources
Resource loading uses the flash calls directly which works on hardware
as the blocklevel abstraction was initialised with a flash structure. On
platforms such as mambo the blocklevel abstraction was initialised with
the bogusdisk structure so calling the flash calls directly results in
following uninitialised function pointers off into lala land.
Functionality is preserved as the blocklevel is told if a flash
partition is ECC protected during the call to ffs_init().
