soc/intel/cmn/tcss: Skip sending CONN IPC command during S3 resume

This patch skips sending CONN IPC command to PMC if system is resuming
from S3.

Sending CONN IPC command as part of `tcss_configure_dp_mode()` function
results into ERROR while system is resuming from S3.

BUG=b:260984500
TEST=Able to test on Google/Rex.

Without this patch:
[ERROR]  pmc_send_ipc_cmd status: fatal
[ERROR]  Port 1 connect request failed
[SPEW ]  [TCSS] TcssInit() - End

With this patch:
No error seen during S3 resume.
