[PATCH] ASoC: SOF: add a pointer to download repo in case FW request fails

[Kai Vehmanen]

The SOF firmware and topology files are not distributed via
linux-firmware. To help debugging cases where correct firmware is
not installed, print a pointer to the official upstream repository
for Sound Open Firmware releases.
