[PATCH v9 04/13] spi: mxic: Provide a capability structure

[Miquel Raynal]

This controller has DTR support, so advertize it with a capability now
that the spi-controller 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.
