Subject: [PATCH v6 3/3] scsi: devinfo: add BLIST_MEDIA_CHANGE for Ultra HS-SD/MMC usb cardreaders

These cardreader devices issue a MEDIA CHANGE unit attention not only
when actually a medium changed but also simply when resuming from suspend.

Setting the BLIST_MEDIA_CHANGE flag enables using runtime pm for SD cardreaders.
