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.
