Subject: [PATCH] reset: imx7: add 'depends on HAS_IOMEM' to fix unmet dependency

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.
https://lkml.org/lkml/2018/2/27/284

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