[PATCH v7 05/14] spi: mxic: Provide a capability structure

This controller has DTR support, so advertize it with a capability now
that the spi_controller_mem_ops structure contains this new field. This
will later be used by the core to discriminate whether an operation is
supported or not, in a more generic way than having different helpers.
