Subject: [PATCH v2 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 make the flag an enum value instead of a pre-processor constant
(more flags will be added to the enum group by another patch).

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

[Bala]: I would recommend to go with QCA_IBS_ENABLED as IBS is
abbreviated as In band sleep.
