Add wait flags to support board/chip specific delays
The NAND flash on the TQM8548_BE modules requires a short delay after running the UPM pattern like the MPC8360ERDK board does. The TQM8548_BE requires a further short delay after writing out a buffer. Normally the R/B pin should be checked, but it's not connected on the TQM8548_BE. The corresponding Linux FSL UPM driver uses similar delay points at the same locations. To manage these extra delays in a more general way, I introduced the "wait_flags" field allowing the board-specific driver to specify various types of extra delay.
