MLK-13616 ARM: imx: Add low power run voltage change support on i.MX6SLL
On i.MX6SLL, if all PLLs is bypassed in low power run mode, we can decrease
the VDD_ARM_IN and VDD_SOC_IN voltage to 0.925V to save power. a 25mV margin
is added to cover IR drop and board tolerance.
Add low power run voltage change support for i.MX6SLL.
