ARM: dts: exynos: Fix BCM4330 Bluetooth reset polarity in I9100

stable inclusion
from stable-v5.10.92
commit 413108ce3b569d3ccfee88ff6d570f0af4801460
bugzilla: 186193 https://gitee.com/openeuler/kernel/issues/I53108

Reference: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=413108ce3b569d3ccfee88ff6d570f0af4801460

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

commit 9cb6de45 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.
