Subject: [PATCH] ARM: dts: rk3036: support wifi/bt for kylin

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.
