spi: gpio: Advertise support for SPI_CS_HIGH
The spi-gpio driver already handles different chip select polarities, but so far this was not advertised in master->mode_bits. This patch fixes mmc_spi on top of spi_gpio, which is useful in some testing scenarios. Signed-off-by: Jonathan Neuschäfer <j.neuschaefer@gmx.net> Signed-off-by: Mark Brown <broonie@kernel.org>
