Subject: [PATCH] arm64/hisilicon: fix SDcard detection

commit 89a5e15bcba8 ("gpio/mmc/of: Respect polarity in the device tree")
has changed how cd_gpios phandle and cd-inverted are used to set gpio's flags.

Since this change, hikey960 SDcard is not detected anymore because flags
are not set correctly. Updating cd-gpios to set GPIO_ACTIVE_LOW instead
of high, fixes the problem.
