Subject: [PATCH 5.4 094/165] staging: axis-fifo: add unspecified HAS_IOMEM dependency

From: Brendan Higgins <brendanhiggins@...gle.com>

[ Upstream commit d3aa8de6b5d0853c43c616586b4e232aa1fa7de9 ]

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.
