Idea is to move spi-nor, mtd-spinor-working is paused because of
non-dm drivers accessing. We are clear that we can't create another
legacy layer to access spi-nor for the sake of non-dm driver to work
which eventually ended-up another mess and also no one take care of
non-dm conversion to dm if we give such feasibility. So we exported a
deadline for full SPI/SPI_FLASH DM conversion till v2018.09. Once all
these relevant conversion done, will try to move.
