In some platforms, they disable the power-supply of i2c due
to power consumption reduction. This patch add bus-supply property.

Although in the most platforms, the power of eeprom
and i2c are alway on, some platforms disable the
eeprom and i2c power in order to meet low power request.
This patch add the pm_runtime ops to control power to
support all platforms.

This patch is squashed from following patch and tested on mt8183 device
which has eeprom at24 client under i2c, so the fix in [2] is also
verified.

When suspending the driver, anx7625_power_standby() will be called to
turn off reset-gpios and enable-gpios. However, power supplies are not
disabled. To save power, the driver can get the power supply regulators
and turn off them in anx7625_power_standby().
