[PATCH v2 14/15] firmware: qcom_scm: Remove SCM PAS wrappers

Newsgroups org.trustedfirmware.lists.op-tee,org.freedesktop.lists.dri-devel,org.infradead.lists.ath12k,org.kernel.vger.linux-arm-msm,org.kernel.vger.linux-devicetree,org.kernel.vger.linux-kernel,org.kernel.vger.linux-media,org.kernel.vger.linux-remoteproc,org.kernel.vger.linux-wireless,org.kernel.vger.netdev
Message-ID <[email protected]> 
From: Sumit Garg <[email protected]>

Now since all the Qcom SCM client drivers have been migrated over to
generic PAS TZ service, let's drop the exported SCM PAS wrappers.
