-ixp4xx updates:
-  - Handle reads that don't start on a half-word boundary.
-  - Make it work when CPU is in little-endian mode.

-+ * Read/write a 16 bit word from flash address 'addr'.
-+ *
-+ * When the cpu is in little-endian mode it swizzles the address lines
-+ * ('address coherency') so we need to undo the swizzling to ensure commands
-+ * and the like end up on the correct flash address.
-+ *
-+ * To further complicate matters, due to the way the expansion bus controller
-+ * handles 32 bit reads, the byte stream ABCD is stored on the flash as:
-+ *     D15    D0
-+ *     +---+---+
-+ *     | A | B | 0
-+ *     +---+---+
-+ *     | C | D | 2
-+ *     +---+---+
-+ * This means that on LE systems each 16 bit word must be swapped. Note that
-+ * this requires CONFIG_MTD_CFI_BE_BYTE_SWAP to be enabled to 'unswap' the CFI
-+ * data and other flash commands which are always in D7-D0.
