mfd: simple-mfd-i2c: Add sl28cpld support
Add the core support for the board management controller found on the
SMARC-sAL28 board.
Also add a virtual symbol which pulls in the simple-mfd-i2c driver and
provide a common symbol on which the subdevice drivers can depend on.
At the moment, this controller is used on the Kontron SMARC-sAL28 board.
