[PATCH 1/1] ARM: dts: rockchip: Wifi improvements for Sonoff iHost

[Hao Zhang]

From: "hao.zhang" <hao.zhang at coolkit.cn>

After some Sonoff-iHosts have been running for a long time, 
the WiFi module will run abnormally.

Adjust the pmu_io_domains and sdio properties 
to solve the WiFi module operation abnormality.
