Mukesh Ojha 9e1d1cbc2a firmware: qcom: scm: Fix __scm and waitq completion variable initialization 
[ Upstream commit 2e4955167e ]

It is possible qcom_scm_is_available() gives wrong indication that
if __scm is initialized while __scm->dev is not and similar issue
is also possible with __scm->waitq_comp.

Fix this appropriately by the use of release barrier and read barrier
that will make sure if __scm is initialized so, is all of its field
variable.

Fixes: d0f6fa7ba2 ("firmware: qcom: scm: Convert SCM to platform driver")
Fixes: 6bf3259922 ("firmware: qcom: scm: Add wait-queue handling logic")
