Subject: [PATCH 1/2] Bluetooth: hci_qca: Rename STATE_<flags> to QCA_<flags>

Rename STATE_IN_BAND_SLEEP_ENABLED to QCA_IN_BAND_SLEEP_ENABLED.
The constant represents a flag (multiple flags can be set at once),
not a unique state of the controller or driver. Also use the BIT()
macro to specify the position of the flag instead of an integer
literal.
