ARM: dts: msm: Modify the "init-voltage" of PON rails for shima 

Setting the "init-voltage" of the PON rails less than the default
voltage leads to momentary voltage dip on the regulator output.
To avoid this behaviour, set the "init-voltage" to a default
recommended value. Also add ACTIVE_ONLY and SLEEP_ONLY nodes for
LDO1C and LDO10C as per the clients requirement to vote for
ACTIVE and SLEEP votes.
