Subject: [PATCH 4.19 158/190] ARM: dts: gemini: Set DIR-685 SPI CS as active low

[ Upstream commit f90b8fda3a9d72a9422ea80ae95843697f94ea4a ]

The SPI to the display on the DIR-685 is active low, we were
just saved by the SPI library enforcing active low on everything
before, so set it as active low to avoid ambiguity.
