4.19-stable review patch. If anyone has any objections, please let me know.

[ Upstream commit 3fb348e030319f20ebbde082a449d4bf8a96f2fd ]
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 Odroid-C1. 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.
