[PATCH 1/2] spi_dw: move spi_dw_chip definition to a header file in include/linux/spi/

[PATCH 1/2] spi_dw: move spi_dw_chip definition to a header file in include/linux/spi/

[Feng Tang]

So that it could be used to setup slave device's platform data, when platform
boot code enumerates and registers those spi slave devices.
