meta-ibm/system1: Add pch-standby service
During the boot process to the BMC Ready state, system1 initiates the
PCH standby power sequence concurrently. The standby power sequence may
not fully complete until the BMC reaches the "Ready" state, as there is
no strict interlock between them.
If the system is powered on after the BMC is Ready, but the PCH standby
is still incomplete, it can lead to boot failure.
This commit introduces a new service that waits for the PCH standby
power sequence to finish by polling the corresponding GPIO pin. This
establishes a hard interlock, ensuring the PCH standby sequence is
complete before the BMC reaches the Ready state.
