Revert "fdt: fix address cell count checking in fdt_translate_address()"
This reverts commit 71105f50fedddfa5b0535d102c3d5078671721ad.
The reverted commit was applied for a temporary to unbreak
few Exynos boards on the release.
After the discussion about the change, this commit should be avoided.
Fixed device-tree for Exynos, allows reverting it without any issues.
