patch 1: This patch can fix bug that controller is still data busy after
reset all blocks. After this patch, I still get data busy in
set_ios().

patch 2: This patch fix bug 'Timeout sending command'. After patch1 and
patch2, there is no mmc errors after:
cd /sys/bus/platform/drivers/dwmmc_rockchip
for i in $(seq 1 10000); do
echo "========================" $i
echo ff0c0000.dwmmc > unbind
sleep .5
echo ff0c0000.dwmmc > bind
sleep 2
done

patch3: This patch fix bug that there is data busy before sdio send CMD53.
But This patch is necessary for sd and mmc too.

Addy Ke (3):
mmc: dw_mmc: update clock after host reach a stable voltage
mmc: dw_mmc: fix bug that cause 'Timeout sending command'
mmc: dw_mmc: Don't start command while data busy
