mtd: spi-nor: add the framework for SPI NOR
This patch cloned most of the m25p80.c. In theory, it adds a new spi-nor layer.
Before this patch, the layer is like:
MTD
------------------------
m25p80
------------------------
spi bus driver
------------------------
SPI NOR chip
After this patch, the layer is like:
MTD
------------------------
spi-nor
------------------------
m25p80
------------------------
spi bus driver
------------------------
SPI NOR chip
With the spi-nor controller driver(Freescale Quadspi), it looks like:
MTD
------------------------
spi-nor
------------------------
fsl-quadspi
------------------------
SPI NOR chip
New APIs:
spi_nor_scan: used to scan a spi-nor flash.
