spi: spi-mem: Add an ecc parameter to the spi_mem_op structure
Soon the SPI-NAND core will need a way to request a SPI controller to
enable ECC support for a given operation. This is because of the
pipelined integration of certain ECC engines, which are directly managed
by the SPI controller itself.
Introduce a spi_mem_op additional field for this purpose: ecc.
So far this field is left unset and checked to be false by all
the SPI controller drivers in their ->supports_op() hook, as they all
call spi_mem_default_supports_op().
