ARM: dts: rk3036: support wifi/bt for kylin

Browse Source 
In order to support the ap6212 module with rockchip wlan driver,
the kylin dts has to change the below for working.

1) We should add the 'supports-sdio' property for mmc tuning,
that's the rockchip private property, not on the upstream.

2) We should add the wifi power control pin and wifi/bt data for dts,
Maybe the history issue, they like the old driver for power
contronlling, the upstream didn't need these for working. we should
remove it in the future.
