[Furquan Shaikh (Code Review)]

Hello Aaron Durbin, Julius Werner, build bot (Jenkins),

I'd like you to reexamine a change.  Please visit

to look at the new patch set (#12).

Change subject: drivers/spi/spi_flash: Clean up SPI flash probe
......................................................................

drivers/spi/spi_flash: Clean up SPI flash probe

1. Rename __spi_flash_probe to spi_flash_generic_probe and export it
so that drivers can use it outside spi_flash.c.
2. Make southbridge intel spi driver use spi_flash_generic_probe if
spi_is_multichip returns 0.
3. Add spi_flash_probe to spi_ctrlr structure to allow platforms to
provide specialized probe functions. With this change, the specialized
spi flash probe functions are now associated with a particular spi
ctrlr structure and no longer disconnected from the spi controller.

BUG=b:38330715
