meta-zaius: Fix up host reference clock after power on

Zaius's host reference clock generator IC requires an output
configuration fixup before trying to send the P9 host any FSI
transactions. The IC is powered by the main 3.3V rail (the BMC runs
from standby 3.3V), so the fixup has to be applied every time after it
is powered on.

Add script that performs the I2C writes to the clock gen.
Add systemd service that launches the script following power on.
Add bitbake recipe to install service.
Add image build append to build service into image.
