  To support the periodic polling mode without stop
caused by CPU idle state, enable delayed timer
as default instead of deferrable timer for
qualcomm platforms.
And change UFS devfreq downdifferential threshold to 65
for less aggresive downscaling.

Please wrap your commit messages at around 70 characters, 50
makes it very hard to read.
