[PATCH] ARM: DT: apq8064: Add sdcc support via mcci driver.

[srinivas.kandagatla]

From: Srinivas Kandagatla <srinivas.kandagatla@linaro.org>

This patch adds support to SD card controller using generic pl180 mmci driver.
This patch also adds temporary fixed regulator to get it going till the actual
regulator is mainlined.
