Subject: [PATCH] Revert "arm64: dts: qcom: qrb5165-rb5: add the Bluetooth node"

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

This reverts commit 71a73864e144aadaa582fe8296ef73fcf3ea7377.

The bluetooth module of the QCA6391 should be represented as consuming
the power outputs of the PMU and not the regulators that are PMU's
inputs. We will be able to model it this way (together with the WLAN
module) once the pwrseq subsystem gets upstream with a dedicated driver
for the PMU.

Thankfully this change has no corresponding DT bindings yet so we can
safely revert adding the bluetooth node.

Fixes: 71a73864e144 ("arm64: dts: qcom: qrb5165-rb5: add the Bluetooth node")
