mtd: spi-nor: intel-spi: Disable write protection only if asked
...
[ Upstream commit cd149eff8d2201a63c074a6d9d03e52926aa535d ]
Currently the driver tries to disable the BIOS write protection
automatically even if this is not what the user wants. For this reason
modify the driver so that by default it does not touch the write
protection. Only if specifically asked by the user (setting writeable=1
command line parameter) the driver tries to disable the BIOS write
protection.

mtd: spi-nor: Prepare core / manufacturer code split
...
Move all SPI NOR controller drivers to a controllers/ sub-directory
so that we only have SPI NOR related source files under
drivers/mtd/spi-nor/.
Rename spi-nor.c into core.c, we are about to split this file in multiple
source files (one per manufacturer, plus one for the SFDP parsing logic).
