Subject: [PATCH] ASoC: Intel: Skylake: Adding support for set system time to
aDSP
In order to calculate the logging timestamps, firmware need the IA
timestamps reference. A new IPC "SYSTEM TIME" has been added to pass
UTC time to firmware. Also enable log skl_log_state_msg structure
for enable log IPC has been modified according to latest firmware
interface specification document.
