spi: Extend the core to ease integration of SPI memory controllers
Some controllers are exposing high-level interfaces to access various kind of SPI memories. Unfortunately they do not fit in the current spi_controller model and usually have drivers placed in drivers/mtd/spi-nor which are only supporting SPI NORs and not SPI memories in general. This is an attempt at defining a SPI memory interface which works for all kinds of SPI memories (NORs, NANDs, SRAMs).
