samsung/exynos5420: add resources during read_resources()
The chipset code was incorrectly adding memory resources
to the domain device after resource allocation occurred.
It's not possible to get the correct view of the address space,
and it's generally incorrect to not add resources during
read_resources(). This change fixes the order by adding resources in
read_resources().
