arm/dt: msm8226: Add helper regulator for vdd_buck of audio codec 



vdd_buck power rail to the codec is supplied by SMPA 4. During
high loading conditions, SMPA4 needs to be backed up by LDO25
as a helper regulator. Add LDO25 as a helper regulator to the
audio codec regulator list. Both SMPA4 and LDO25 are optional
and on-demand regulators for the audio codec.
