dt-bindings: ufs: samsung,exynos-ufs: Add size constraints on "samsung,sysreg"

Browse Source 
The 'phandle-array' type is a bit ambiguous. It can be either just an
array of phandles or an array of phandles plus args. "samsung,sysreg" is
the latter and needs to be constrained to a single entry with a phandle and
offset.
