iommu/omap: Fix a typo in the public omap-iommu.h fileHEADiommu-linux-4.19.y

The commit b8ee97c59fb1 ("iommu/omap: introduce new API for
runtime suspend/resume control") has introduced two new functions
omap_iommu_domain_deactivate() & omap_iommu_domain_activate(),
and has also added their stubs to allow COMPILE_TEST of consumer
drivers using this header file. The return values in these stubs
used a wrong error value of ENOTSUP instead of ENOTSUPP. Fix this
typo. While at this, include the errno header file that defines
this macro as well to make the omap-iommu.h self-contained.
