[U-Boot] [PATCH v2 07/17] dm: spi: Use device_bind_driver() instead of our own function

[Simon Glass]

The SPI function does the same thing, so we may as well just use the new
generic function. The 'cs' parameter was not actually used, so can be
dropped.

Changes in v2:
- Add new patches to adjust SPI to use device_bind_driver()
