mfd: Add companion chip in 88pm80x
in hw design, 800 is mainly for pmic control, while 805 for audio. but there are 3 registers which controls class D speaker property, and they are defined in 800 i2c client domain. so 805 codec driver needs to use 800 i2c client to access class D speaker reg for audio path management. so add this workaround for the purpose to let 805 access 800 i2c in some scenario.
