mfd: simple-mfd-i2c: Add Delta TN48M CPLD support

Browse source

[ Upstream commit 8f34c1a64c ]

Delta TN48M switches have a Lattice CPLD that serves
multiple purposes including being a GPIO expander.

So, lets use the simple I2C MFD driver to provide the MFD core.

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.
