ARM: dts: samsung: exynos4412-midas: turn off SDIO WLAN chip during system suspend

Browse source

[ Upstream commit 2ff147fdfa ]

Commit 8c3170628a ("wifi: brcmfmac: keep power during suspend if board
requires it") changed default behavior of the BRCMFMAC driver, which now
keeps SDIO card powered during system suspend to enable optional support
for WOWL. This feature is not supported by the legacy Exynos4 based
boards and leads to WLAN disfunction after system suspend/resume cycle.
Fix this by annotating SDIO host used by WLAN chip with
'cap-power-off-card' property, which should have been there from the
beginning.
