power: domain: meson-ee-pwrc: use dev_read_phandle_with_args for ao-sysctrl

Replace the manual ofnode_read_u32() + ofnode_get_by_phandle() sequence
with a single dev_read_phandle_with_args() call to resolve the
amlogic,ao-sysctrl phandle. This is cleaner and avoids the intermediate
phandle value and ofnode_valid() check.

No functional change.
