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).

	  This enables support for the Firmware Memory controller (FMC)

	  in the Aspeed AST2500/AST2400 SoCs when attached to SPI NOR chips,

	  and support for the SPI flash memory controller (SPI) for

	  the host firmware. The implementation only supports SPI NOR.

	  Cadence QSPI is a specialized controller for connecting an SPI

	  Flash over 1/2/4-bit wide bus. Enable this option if you have a
