spi: dw: remove unused dw_spi_chip handling
The path of code using this struct is unused since there is no more user of this. Remove code and struct definition. Signed-off-by: Clement Leger <cleger@kalray.eu> Link: https://lore.kernel.org/r/20200416110916.22633-1-cleger@kalray.eu Signed-off-by: Mark Brown <broonie@kernel.org>
