pm: add suspend_mem and suspend_standby support

Today when we go to suspend we can not knwon at drivers level if we go in
STANDBY or MEM. Fix this by introducing two new callback suspend_mem and
suspend_standby.

If a bus or drivers does not need to care about this distinction we fallback to
suspend. This will allow to do not update the current bus or drivers.

This is needed as example by at91 OHCI, UDC and atmel serial
