This series is combination of mtd and sf tunning stuff in previous
version patches.

This is whole patch series for add mtd support to spi-flash
framework and related stuff.

The idea is to introduce the spi-nor flash framework which
similar to Linux with driver-model support.

spi-nor looks:

-----------------------------------------------------------
    cmd_spi                 cmd_sf
------|----------------------------------------------------
      |                    spi_flash
------|----------------------------------------------------
      |                     MTD Core
------|----------------------------------------------------
      |                     sf-uclass
------|----------------------------------------------------
      |                   SPI-NOR Core
------V----------------------------------------------------
   spi-uclass <---->spi-nor-flash         drivers/mtd/spi/*
-----------------------------------------------------------
  drivers/spi/*
-----------------------------------------------------------

drivers/mtd/spi/spi-nor.c: spi-nor core
drivers/mtd/spi/spi-flash-nor.c: spi-nor to spi drivers interface
drivers/mtd/spi/fsl-quadspi.c: spi-nor controller driver

Changes in this series:
- drivers/mtd/spi/sf_probe.c: spi-flash to spi drivers interface(dm and non-dm)
- drivers/mtd/spi/sf_ops.c: Core spi-flash functionalities.
- spi_flash ops and dm_spi_ops are not needed as flash opertaion are
  common for dm and non-dm via MTD

Changes in v5, v6, v3, v2:
	- One patch bisectable separation
	- Rebase to master
	- added newly mtd stuff patches.
