Subject: [PATCH v2 3/3] arm: dts: mt7623: fix card detection issue on bananapi-r2

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

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

Cc: stable@...r.kernel.org
Fixes: 0eed8d097612 ("arm: dts: mt7623: Add SD-card and EMMC to bananapi-r2")
