Subject: [PATCH 4.15 031/163] arm: dts: mt7623: fix card detection issue on bananapi-r2

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

------------------

From: Sean Wang <sean.wang@...iatek.com>

commit b96a696fb2a8dd1ee4e6cfee48dcac270fc53287 upstream.

Fix that bananapi-r2 booting from SD-card would fail since incorrect
polarity is applied to the previous setup with GPIO_ACTIVE_HIGH.
