[PATCH v2 10/14] spi: Introduce setup_for_spinand()

[Christian Marangi <ansuelsmth@gmail.com>]

A common device attached to SPI are SPI NAND and some device might
require to have info on the attached NAND to know the flash page size
and spare size.

To support this, introduce setup_for_spinand() that pass the attached
spinand info from manufacturer.
