Update flash drivers to support QuadSPI

Browse source 
- Update flash w25n01g driver to support QuadSPI.

- flash_m25p16 update for QuadSPI support

- w25m driver update for QuadSPI support

- Use 100Mhz (ULTRAFAST) clock for QuadSPI w25n01

- Conditionalize QUADSPI code in w25n01g driver

- Use handle instead of handle_u
