staging: axis-fifo: add unspecified HAS_IOMEM dependency

Currently CONFIG_XIL_AXIS_FIFO=y implicitly depends on
CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get
the following build error:

ld: drivers/staging/axis-fifo/axis-fifo.o: in function `axis_fifo_probe':
drivers/staging/axis-fifo/axis-fifo.c:809: undefined reference to `devm_ioremap_resource'

Fix the build error by adding the unspecified dependency.

          This adds support for the Xilinx AXI-Stream FIFO IP core driver.
          The AXI Streaming FIFO allows memory mapped access to a AXI Streaming
