mtd: spi: Export spi_flash_std_probe()
With of-platdata we need to create drivers for particular chips, or at
least drivers that are separate from the standard code, since C structures
are created by dtoc which are private to that driver.
To avoid duplicating the probing code, export this probe function for use
by these drivers.
