This config select's MFD_SYSCON, but does not depend on HAS_IOMEM.

Compile testing on architecture without HAS_IOMEM causes "unmet
direct dependencies" in Kconfig phase.

Detected by "make ARCH=score allyesconfig".

Arnd Bergmann and I discussed how to fix unmet dependency of MFD_SYSCON.

We agreed to add 'depends on HAS_IOMEM' to drivers causing
unmet dependency.
