davinci: rootdir: init.qcom.rc: Tuning UFS clock scaling during boot time

Browse Source 
Disabling UFS clock scaling during boot time helps in reducing
IO delays, which helps in reducing the total boot time.
This change will disable UFS clock scaling during early-init and
enable it back after boot completion.
