ARM: dts: n900: fix mmc1 card detect gpio polarity

spinal84 · tmlind · commit ac9c908eecde · 2019-01-23T16:14:15.000-08:00
Wrong polarity of card detect GPIO pin leads to the system not booting from external mmc, if the back cover of N900 is closed. When the cover is open the system boots fine. This wasn't noticed before, because of a bug, which was fixed by commit e63201f (mmc: omap_hsmmc: Delete platform data GPIO CD and WP). Kernels up to 4.19 ignored the card detect GPIO from DT.
