Bluetooth: hci_qca: fix QCA6390 support on non-DT platforms
QCA6390 can albo be used on non-DT systems so we must not make the power
sequencing the only option. Check if the serdev device consumes an OF
node. If so: honor the new contract as per the DT bindings. If not: fall
back to the previous behavior by falling through to the existing
default label.
Fixes: 9a15ce685706 ("Bluetooth: qca: use the power sequencer for QCA6390")
