bus: ti-sysc: Fix missing force mstandby quirk handling
[ Upstream commit 93c60483b5feefced92b869d5f97769495bc6313 ]
Commit 03856e928b0e ("bus: ti-sysc: Handle mstandby quirk and use it for
musb") added quirk handling for mstandby quirk but did not consider that
we also need a quirk variant for SYSC_QUIRK_FORCE_MSTANDBY.
We need to use forced idle mode for both SYSC_QUIRK_SWSUP_MSTANDBY and
SYSC_QUIRK_FORCE_MSTANDBY, but SYSC_QUIRK_SWSUP_MSTANDBY also need to
additionally also configure no-idle mode when enabled.
Fixes: 03856e928b0e ("bus: ti-sysc: Handle mstandby quirk and use it for musb")
