dmaengine: QCOM_HIDMA_MGMT depends on HAS_IOMEM

[ Upstream commit 0cfbb589d67f16fa55b26ae02b69c31b52e344b1 ]

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.

Rectifies these build errors:
s390-linux-ld: drivers/dma/qcom/hidma_mgmt.o: in function `hidma_mgmt_probe':
hidma_mgmt.c:(.text+0x780): undefined reference to `devm_ioremap_resource'
s390-linux-ld: drivers/dma/qcom/hidma_mgmt.o: in function `hidma_mgmt_init':
hidma_mgmt.c:(.init.text+0x126): undefined reference to `of_address_to_resource'
s390-linux-ld: hidma_mgmt.c:(.init.text+0x16e): undefined reference to `of_address_to_resource'
