MLK-12478-1 can: flexcan: add LPSR mode support

For MX7D LPSR mode, the controller will lost power and got the
configuration state lost after system resume back.
So we need to set pinctrl state again and re-start chip to do
re-configuration after resume.

For wakeup case, we also need re-configure the chip in case the state
got lost. For interface is not up before suspend case, we don't need
re-configure as it will be configured by user later by interface up.
