Subject: [PATCH v3 1/2] Bluetooth: hci_qca: Rename STATE_<flags> to QCA_<flags>

Rename STATE_IN_BAND_SLEEP_ENABLED to QCA_IBS_ENABLED. The constant
represents a flag (multiple flags can be set at once), not a unique
state of the controller or driver.

Also make the flag an enum value instead of a pre-processor constant
(more flags will be added to the enum group by another patch).

Signed-off-by: Matthias Kaehlcke <mka@...omium.org>

Changes in v3:
- rename STATE_IN_BAND_SLEEP_ENABLED to QCA_IBS_ENABLED

Changes in v2:
- don't use BIT()
- change to enum type
- updated commit message
