pmdomain: mtk-pm-domains: Fix spinlock recursion fix in probe
Remove scpsys_get_legacy_regmap(), replacing its usage with
of_find_node_with_property(). Explicitly call of_node_get(np) before each
of_find_node_with_property() to maintain correct node reference counting.
The of_find_node_with_property() function "consumes" its input by calling
of_node_put() internally, whether or not it finds a match. Currently,
dev->of_node (np) is passed multiple times in sequence without incrementing
its reference count, causing it to be decremented multiple times and
risking early memory release.
Adding of_node_get(np) before each call balances the reference count,
preventing premature node release.
