The SDcard detection of hikey960 is active low so cd-inverted is wrong.
Instead of adding cd-inverted, we should better set correctly cd-gpios
to use GPIO_ACTIVE_LOW.

SD card detection was not working on v5.0-rc1 but patch
https://marc.info/?l=linux-mmc&m=154637189021211&w=2 makes it work.
Nevertheles, latest changes in of_mmc_detection makes possible to have 
a correct DT config.
