ARM: dts: Add keep-power-in-suspend to WiFi SDIO node for exynos5250-snow
The Marvell mwifiex driver prevents the system to enter into a suspend state if the card power is not preserved during a suspend/resume cycle. So Suspend-to-RAM and Suspend-to-idle are failing on Exynos5250 Snow. Add the keep-power-in-suspend Power Management property to the SDIO/MMC node so the mwifiex suspend handler doesn't fail and the system is able to enter into a suspend state.
