Subject: [PATCH AUTOSEL 4.18 12/56] bus: ti-sysc: Fix no_console_suspend
 handling

From: Tony Lindgren <tony@...mide.com>

[ Upstream commit 4f3530f4a41d49c41015020cd9a5ed5c95b5d2db ]

If no_console_suspend is set, we should keep console enabled during suspend.
Lets fix this by only producing a warning if we can't idle hardware during
suspend.
