accel/qaic: Support MHI QAIC_TIMESYNC channel
Use QAIC_TIMESYNC MHI channel to send UTC time to device in SBL
environment. Remove support for QAIC_TIMESYNC MHI channel in AMSS
environment as it is not used in that environment.

accel/qaic: Add support for periodic timesync
Device and Host have a time synchronization mechanism that happens once
during boot when device is in SBL mode. After that, in mission-mode there
is no timesync. In an experiment after continuous operation, device time
drifted w.r.t. host by approximately 3 seconds per day. This drift leads
to mismatch in timestamp of device and Host logs. To correct this
implement periodic timesync in driver. This timesync is carried out via
QAIC_TIMESYNC_PERIODIC MHI channel.
