ARM: dts: Don't put SDHC1's vdd-io regulator in lpm for msm8610 CDP/MTP

The vdd-io regulator for eMMC powers the controller inside the eMMC
device. Setting this regulator to lpm mode when the device goes to sleep
might restrict the amount of power that the card can draw. This might
lead to undeterministic behavior and thereby put the card in bad state,
hence don't set this regulator to lpm.
