ARM: dts: exynos: Fix BCM4330 Bluetooth reset polarity in I9100
commit 9cb6de45a006a9799ec399bce60d64b6d4fcc4af upstream.
The reset GPIO was marked active-high, which is against what's specified
in the documentation. Mark the reset GPIO as active-low. With this
change, Bluetooth can now be used on the i9100.
