+ AVR32: Initialize bi_flash* in board_init_r
+
+ The ATSTK1000-specific flash driver intializes bi_flashstart,
+ bi_flashsize and bi_flashoffset, but other flash drivers, like the CFI
+ driver, don't.
+
+ Initialize these in board_init_r instead so that things will still be
+ set up correctly when we switch to the CFI driver.
