mmc: Add long power off notification support
At the moment only POWER_OFF_SHORT is sent to the device in case the host
is suspended. This patch adds the support of sending POWER_OFF_LONG
notification in case the device is powered off.
According to device vendors the POWER_OFF_LONG notification will shorten
the initialization time of the eMMC card during next boot up.
