Subject: [PATCH 1/3] mfd: simple-mfd-i2c: add compatible string for LS1028A-QDS FPGA

As Michael mentions in the description of commit 3abee4579484 ("mfd: Add
simple regmap based I2C driver"), "If a device wants to use this as its
MFD core driver, it has to add an individual compatible string."

The QIXIS FPGA on the LS1028A-QDS boards has a similar purpose to the
Kontron SL28 CPLD: it deals with board power-on reset timing, muxing,
etc.
