- Fix a bugfix of v2 in checking spi memory operation.
- split read_dma function into two (normal/bounce)
- Support 7bytes generic spi xfer

Changes in v2:
- Add power management support
- Fix bugs in checking spi memory operation.
- use dma_alloc_coherent for allocating bounce buffer
- code cleanups
