Subject: [PATCH 2/2] Bluetooth: qca: run the power-on/off sequence for QCA6390 too

From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>

The Bluetooth module on QCA6390 needs to be powered-on by enabling the
relevant regulators and driving the enable GPIO high. We can reuse the
power sequence for the WNC models.
