When the power is controlled by a power sequencer, whether the host can gate it depends on the hardware wiring, e.g. the presence of the BT_EN or W_DISABLE2# line. Query the generic pwrseq_is_controllable() helper whenever the BT power comes from a sequencer, regardless of which provider it is (M2, WCN, ...). If the power is not controllable, clear 'bt_en_available' so that HCI_QUIRK_NON_PERSISTENT_SETUP is not set. This is based on Manivannan's original patch that keyed the decision off the W_DISABLE2# device tree property, it now uses the generic pwrseq helper and handles the always-on case.
