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.
Additionally, skip `configure_aux_bias_pads()` during S3 resume.
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.
