soc: qcom: sysmon: Enable back MSM_SYSMON_COMM interface support

MSM_SYSMON_GLINK_COMM is currently enabled for all targets which breaks
few existing targets, which do not support GLINK protocol and therefore
are still dependent on MSM_SYSMON_COMM support. Enable back sysmon
communication over SMD interface to preserve backward compatibility
until all targets support GLINK.
