ARM: dts: msm: reduce CPR turbo floor voltage for msm8226



The device tree property qti,cpr-cond-min-voltage = <1140000> along with
an appropriate qti,cpr-cond-min-volt-fuse property value ensure that the
CPR turbo floor voltage is restricted to 1.14 V on devices that cannot
operate at lower voltages.

Therefore, reduce the default CPR turbo floor voltage to 1.1 V in order
to save power on devices that can operate at the lower voltage.
