we should send hci reset command before bt turn off, which can reset bt
firmware status.

thanks for your explanation.
you are right. @lest should be used as reference point to compare.

serdev_device_write() is not appropriate at here because
serdev_device_write_wakeup() is not used to release completion hold
by the former at @write_wakeup member of struct serdev_device_ops.
Fix by using serdev_device_write_buf() instead of serdev_device_write().

in page fault after overwriting memdump buffer allocated.
Fixed by ignoring QCA6390 sequence number check and

Warm reboot can not reset controller qca6390 due to
lack of controllable power supply, so causes firmware
download failure during enable.
Fixed by sending VSC EDL_SOC_RESET to reset qca6390
within added device shutdown implementation.

@dev parameter of qca_suspend()/qca_resume() represents
serdev_device, but it is mistook for hci_dev and causes
succedent unexpected memory access.
Fix by taking @dev as serdev_device.
