dmaengine: ALTERA_MSGDMA depends on HAS_IOMEM
When CONFIG_HAS_IOMEM is not set/enabled, certain iomap() family
functions [including ioremap(), devm_ioremap(), etc.] are not
available.
Drivers that use these functions should depend on HAS_IOMEM so that
they do not cause build errors.
Repairs this build error:
s390-linux-ld: drivers/dma/altera-msgdma.o: in function `request_and_map':
altera-msgdma.c:(.text+0x14b0): undefined reference to `devm_ioremap'
Fixes: a85c6f1b2921 ("dmaengine: Add driver for Altera / Intel mSGDMA IP core")
