drm/bridge/synopsys: dsi: explicitly request exclusive reset control
Based on patch "Convert drivers to explicit reset API" from Philipp Zabel
Commit a53e35db70d1 ("reset: Ensure drivers are explicit when requesting
reset lines") started to transition the reset control request API calls
to explicitly state whether the driver needs exclusive or shared reset
control behavior. Convert all drivers requesting exclusive resets to the
explicit API call so the temporary transition helpers can be removed.
No functional changes.
