ARM: dts: exynos: Add support for wlan to Artik 5
On the Artik 520 module, there is a bcm4354 attached to mshc_1. Enable it and turn on the regulator used for it, so that both WiFi & Bluetooth will work. Verified to work on the Artik 520 evaluation board. Signed-off-by: Michael Lyle <mlyle@lyle.org> Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
