[PATCH 1/3] firmware: qcom-scm: Initialize waitq before setting global __scm

[Unnathi Chalicheemala <quic_uchalich@quicinc.com>]

Suppose there's another device probing at the same time as SCM driver.
It calls into SCM and triggers WAITQ sleep but waitq completion
structure may not be initialized yet.
Fix this by moving initialization of waitq before setting global __scm.

Fixes: 6bf325992236 ("firmware: qcom: scm: Add wait-queue handling logic")
