can: flexcan: add LPSR mode support
On the i.MX7D in LPSR mode, the controller will be powered off and the
configuration state is lost after system resume. Upcoming i.MX8QM/QXP
will also completely power off the domain, the controller state is lost
and needs restore, too. So we need to set the pinctrl state again and
re-start chip to re-configuration after resume.
For the wakeup case, it should not set pinctrl to sleep state by
pinctrl_pm_select_sleep_state.
If the interface is down before suspend, we don't need to re-configure
it as it will be configured if the interface is brought up later.
