commit 32a1671ff8e84f0dfff3a50d4b2091d25e91f5e2 upstream. Recent changes in the SPI core and the SPI-GPIO driver revealed that the GPIO lines for the LD9040 LCD controller on the UniversalC210 board are defined incorrectly. Fix the polarity for those lines to match the old behavior and hardware requirements to fix LCD panel operation with recent kernels.
