driver: bluetooth: hci_qca:fix unable to load the BT driver
[ Upstream commit db0ff7e15923ffa7067874604ca275e92343f1b1 ]
Some modules have BT_EN enabled via a hardware pull-up,
meaning it is not defined in the DTS and is not controlled
through the power sequence. In such cases, fall through
to follow the legacy flow.
