[v2,0/2] accel/qaic: Add support for host/device timesync

Message

AIC100 supports a timesync mechanism that allows AIC100 to timestamp
device logs with a host based time. This becomes useful for putting host
logs in a unified timeline with device logs for debugging and performance
profiling. The mechanism consists of a boot-time initialization and a
runtime perodic resync to counteract the effects of time source drift
over time between the host and device.

v2:
- Fix readq usage on 32-bit powerpc
- Fix doc warning due to trailing "_"
