mtd: hyperbus: fix dependency and build error

lib/devres.c, which implements devm_ioremap_resource(), is only built
when CONFIG_HAS_IOMEM is set/enabled, so MTD_HYPERBUS should depend
on HAS_IOMEM.  Fixes a build error and a Kconfig warning (as seen on
UML builds):

WARNING: unmet direct dependencies detected for MTD_COMPLEX_MAPPINGS
  Depends on [n]: MTD [=m] && HAS_IOMEM [=n]
  Selected by [m]:
  - MTD_HYPERBUS [=m] && MTD [=m]

ERROR: "devm_ioremap_resource" [drivers/mtd/hyperbus/hyperbus-core.ko] undefined!
