ASoC: SOF: IPC4: update gain ipc msg definition to align with fw
Recent firmware changes modified the curve duration from 32 to 64 bits, which breaks volume ramps. A simple solution would be to change the definition, but unfortunately the ASoC topology framework only supports up to 32 bit tokens. This patch suggests breaking the 64 bit value in low and high parts, with only the low-part extracted from topology and high-part only zeroes. Since the curve duration is represented in hundred of nanoseconds, we can still represent a 400s ramp, which is just fine. The defacto ABI change has no effect on existing users since the IPC4 firmware has not been released just yet.
