4.20-stable review patch. If anyone has any objections, please let me know.
------------------
[ Upstream commit c8bfe65fb1fb7a43d766df1dfa379406112cba61 ]
After commit 89a5e15bcba87d ("gpio/mmc/of: Respect polarity in the device
tree") SD cards are not detected anymore.
The CD GPIO is "active low" on the EC-100. The MMC dt-bindings specify:
"[...] using the "cd-inverted" property means, that the CD line is active
high, i.e. it is high, when a card is inserted".
Fix the description of the SD card by marking it as GPIO_ACTIVE_LOW and
drop the "cd-inverted" property. This makes the definition consistent
with the existing dt-bindings and fixes the check whether an SD card is
inserted.
