Subject: [PATCH v4 5/9] mfd: simple-mfd-i2c: Add support for tsd,mule

Mule is an MCU that emulates a set of I2C devices, among which an amc6821
device and an I2C mux that exposes more emulated devices. These two devices
share the same I2C address. Only the I2C mux uses register (0xff) as a
config register.

Add a simple-mfd-i2c driver support for these two sub-devices.
