ARM: dts: qcom: change vdd io current level of sdhc_2 for Sun

Browse Source 
Change vdd io current level of sdhc_2 to set 22 mA load to follow
up new Power Grid on SDC2 vdd-io pads regulator lpk. The previous
5.6 mA is not able to reflect real drawing current. It may cause
OCP issue as 5.6 mA voting load from SW is not enough to let SDC2
vdd-io regulator work on HPM, but the real drawing current may
exceed LPM OCP threshold.
