Two MTD fixes, for the pxa3xx-nand driver:

- This driver was not ready to fully Armada 370 NAND, with particularly
    notable problems seen on flash with 2KB page sizes. This "compatible" entry
    really should have been held back until 3.14 or later.
 
  - Fix a bug seen in rare cases on the error path of a failed probe attempt,
    where we free unallocated DMA resources
