ARM: dts: samsung: universal_c210: turn off SDIO WLAN chip during system suspend

[ Upstream commit 97aee67e2406ea381408915e606c5f86448f3949 ]

Commit 8c3170628a9c ("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.
