Subject: [PATCH v2 2/6] mfd: simple-mfd-i2c: add compatible string for Layerscape QIXIS CPLD

The QIXIS CPLD found on Layerscape boards such as LX2160AQDS, LS1028AQDS
etc deals with power-on-reset timing, muxing etc. Use the simple-mfd-i2c
as its core driver by adding an individual compatible string for each
board. By using the simple-mfd-i2c driver any child device will have
access to the i2c regmap created by it.
