[PATCH] mmc: core: propagate removable attribute to driver core

[Thomas Weißschuh]

Userspace can use this to distinguish hotpluggable mmc devices such as
sdcards from non-hotpluggable ones such as eMMC.
One example is the lsblk tool from util-linux.

Note that dev_set_removable() is not related to GENHD_FL_REMOVABLE which
is not applicable as per the comment in drivers/mmc/core/block.c
