[PATCH 1/6] arm64: Unconditionally call unflatten_device_tree()

[Stephen Boyd <sboyd@kernel.org>]

Call this function unconditionally so that we can populate an empty DTB
on platforms that don't boot with a firmware provided or builtin DTB.
There's no harm in calling unflatten_device_tree() unconditionally. If
there isn't a valid initial_boot_params dtb then unflatten_device_tree()
returns early.
