PCI: imx6: Explicitly request exclusive reset control

Commit a53e35db ("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.
