Bluetooth: hci_qca: don't call pwrseq_power_off() twice for QCA6390

Now that we call pwrseq_power_off() for all models that hold a valid
power sequencing handle, we can remove the switch case for QCA_6390. The
switch will now use the default label for this model but that's fine: if
it has the BT-enable GPIO than we should use it.
