commit 235b630eda072d7e7b102ab346d6b8a2c028a772 upstream.
This commit reintroduces interrupt-based card detection previously
used in the rts5139 driver. This functionality was removed in commit
00d8521dcd ("staging: remove rts5139 driver code").
Reintroducing this mechanism fixes presence detection for certain card
readers, which with the current driver, will taken approximately 20
seconds to enter S3 as `mmc_rescan` has to be frozen.
