[ Upstream commit a57f68ddc8865d59a19783080cc52fb4a11dc209 ]

Most likely due to copy-paste mistake the device managed version of the
denoted reset control getter has been implemented with invalid semantic,
which can be immediately spotted by having "WARN_ON(shared && acquired)"
warning in the system log as soon as the method is called. Anyway let's
fix it by altering the boolean arguments passed to the
__devm_reset_control_bulk_get() method from
- shared = true, optional = false, acquired = true
to
+ shared = false, optional = true, acquired = true
That's what they were supposed to be in the first place (see the non-devm
version of the same method: reset_control_bulk_get_optional_exclusive()).
