ASoC: sigmadsp: Refuse to load firmware files with a non-supported version

Browse source

commit 50c0f21b42 upstream.

Make sure to check the version field of the firmware header to make sure to
not accidentally try to parse a firmware file with a different layout.
Trying to do so can result in loading invalid firmware code to the device.
