Subject: [PATCH] ARM: dts: exynos: Fix BCM4330 Bluetooth reset polarity in I9100

Git-commit: 9cb6de45a006a9799ec399bce60d64b6d4fcc4af

Patch-mainline: v5.17-rc1

References: git-fixes

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.
