Revert "PCI: qcom: Disable write access to read only registers for IP v2.3.3"

This reverts commit 35c95eda7b6d9883d1cc9bb1f89d454baa140ebc which is
commit a33d700e8eea76c62120cb3dbf5e01328f18319a upstream.

It was applied to the incorrect function as the original function the
commit changed is not in this kernel branch.
