[PATCH 03/12] power: sequencing: qcom-wcn: Add support for 'is_fixed()' callback to 'bluetooth' target

[Manivannan Sadhasivam via B4 Relay <devnull+manivannan.sadhasivam.oss.qualcomm.com@kernel.org>]

From: Manivannan Sadhasivam <manivannan.sadhasivam@oss.qualcomm.com>

Add support for 'is_fixed()' callback to indicate the consumers whether
this power sequencer target 'bluetooth' is fixed or controllable. This is
decided based on the availability of the 'bt-enable' GPIO in DT.
