soc: qcom: pmic_glink: Fix boot when QRTR=m
We need to bail out before adding/removing devices if we are going to
-EPROBE_DEFER. Otherwise boot can get stuck in a probe deferral loop due
to a long-standing issue in driver core (see commit fbc35b45f9f6 ("Add
documentation on meaning of -EPROBE_DEFER")).
Deregistering the altmode child device can potentially also trigger bugs
in the DRM bridge implementation, which does not expect bridges to go
away.
