mfd: cs5535: Don't build on UML

The cs5535-mfd driver uses CPU-specific data that is not available
for ARCH=um builds, so don't allow it to be built for UML.

Prevents these build errors:

This is the core driver for CS5535/CS5536 MFD functions. This is
necessary for using the board's GPIO and MFGPT functionality.
