soc: qcom: pmic_glink: Avoid losing early rpmsg probe
The PMIC GLINK rpmsg device can appear before the platform device has
finished probing. In that case pmic_glink_rpmsg_probe() sees
__pmic_glink as NULL and returns -ENODEV, which is treated as a fatal
probe failure for the rpmsg endpoint.
If this race is hit, pg->ept is never installed and PMIC GLINK clients
never receive the service-up notification. This may leave the system
with no Type-C functionality and without battery/power supply
management.
Return -EPROBE_DEFER when the rpmsg endpoint arrives before the platform
device is ready.
