Firmware command timeouts (-11) suggest that wrong board file was used
to boot the device.

The currently available board-2.bin doesn't seem to include your
device (168c:003e:144d:412f). You can list them with:

; strings board-2.bin | grep vendor
bus=pci,vendor=168c,device=003e,subsystem-vendor=168c,subsystem-device=3361m
bus=pci,vendor=168c,device=003e,subsystem-vendor=168c,subsystem-device=3362m
bus=pci,vendor=168c,device=003e,subsystem-vendor=168c,subsystem-device=3363m

Was this run on 4.4 or 4.2?

The board-2.bin support was added in 4.4. Prior to this the driver
would try to load the board-pci-xxx. files. You can:
 a) scream louder and complain to your card vendor and/or qualcomm
 b) use pre-4.4 kernel, get windows driver, extract .inf and eeprom
files from it, look for the one that matches your device
(168c:003e:144d:412f) and use it as board-pci-168c:003e:144d:412f.bin
