iommu/exynos: prevent building on big-endian kernels
Since we print the correct warning, an allmodconfig build is no longer
clean but always prints it, which defeats compile-testing:
drivers/iommu/exynos-iommu.c:58:2: error: #warning "revisit driver if we can enable big-endian ptes" [-Werror=cpp]
This replaces the #warning with a dependency, moving warning text into
a comment.
Fixes: 1f59adb1766d ("iommu/exynos: Replace non-existing big-endian Kconfig option")
