Wei Xu: This fixes a functional regression with wifi on the HiKey
board that was introduced in 4.18-rc with commit 60f36637bbbd
("wlcore: sdio: allow pm to handle sdio power").

Wei Xu: Just wanted to follow up to make sure this wasn't missed for
4.18-rc, as I haven't seen it upstream or in -next, and it fixes a
recently introduced regression.
