ath10k-firmware: update Candela Tech firmware images

Release notes since last update:

wave-1 firmware:

*  Feb 14, 2019:  Remove logic that causes assert when swba logic is not
                  initialized. This was seen when trying to bring up 6 VAP
                  vdevs. A similar fix went into wave-2 firmware some time
                  ago.

*  Feb 27, 2019:  Support up to 32 vAP vdevs, fix stack corruption when
                  driver requests too many vAP.

*  Feb 28, 2019:  Support beacon-tx-wmi callback message. This lets driver
                  properly clean up beacon buffers so we don't crash
                  (somethings the entire OS/system) due to DMA errors.

wave-2 firmware:

*  Feb 27. 2019:  Support up to 32 AP vdevs. Previous to this, stack would
                  be corrupted if you went past 16 AP vdevs.

*  Feb 28, 2019:  Support beacon-tx-wmi callback message. This lets driver
                  properly clean up beacon buffers. In wave-1, this could
                  crash the entire OS, but I didn't see the same crashes
                  in wave-2, so maybe it is fixed in some other way. Add
                  the feature regardless as it seems proper.
