Subject: [PATCH 5.2 031/124] bus: ti-sysc: Fix handling of forced idle

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

[ Upstream commit 6ee8241d17c68b94a91efabfd6bdfe63bb1b79c1 ]

For some devices we can get the following warning on boot:

ti-sysc 48485200.target-module: sysc_disable_module: invalid midlemode

Fix this by treating SYSC_IDLE_FORCE like we do for the other bits
for idlemodes mask.

Fixes: d59b60564cbf ("bus: ti-sysc: Add generic enable/disable functions")
