usb: enable media-presence polling for SD cards

After USB enumeration, some SD card readers do not send signals to the
device when the SD card is inserted or removed.

To support SD card hotplugging, this patch enables in-kernel
media-presence polling, which will check the SD card status every 2
seconds after a SD card reader is attached.

Bug: 186479576
Test: SD card insertion/removal and data copy (see b/301566595)
