i2c: imx-lpi2c: add VLLS mode support
When system enters VLLS mode, module power is turned off. As a result,
all registers are reset to HW default value. After exiting VLLS mode,
registers are still in default mode. As a result, the pinctrl settings
are incorrect, which will affect the module function.
The patch recovers the pinctrl setting when exit VLLS mode.
