Subject: [PATCH v1 4/5] ptp: 1588_clock_ines: add unspecified HAS_IOMEM dependency

Currently CONFIG_PTP_1588_CLOCK_INES=y implicitly depends on
CONFIG_HAS_IOMEM=y; consequently, on architectures without IOMEM we get
the following build error:

/usr/bin/ld: drivers/ptp/ptp_ines.o: in function `ines_ptp_ctrl_probe':
drivers/ptp/ptp_ines.c:795: undefined reference to `devm_ioremap_resource'

Fix the build error by adding the unspecified dependency.
