[ Impact ]

Currently, the 'wrong' firmware is loaded because Qualcomm hasn't
released the correct one until recently. This results in poor bluetooth
performance.

Firmware finally landed in upstream linux-firmware:

https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-
firmware.git/commit/?id=77a11ffc5a0aaaadc870793d02f6c6781ee9f598


[ Test Plan ]

Boot and check that the new firmware is loaded and that bluetooth connections 
can be established.

[    6.159831] Bluetooth: hci0: QCA Downloading qca/hpbtfw21.tlv


[ Where Problems Could Occur ]

New firmware that is only loaded on specific Qualcomm HW. Should not
affect any other users.
