[ Upstream commit 15d7b3dfafa98270eade6c77d2336790dde0a40d ]
Current implementation requires syscon compatible for pio property which is used for driving the switch leds on mt7988.
Replace syscon_regmap_lookup_by_phandle with of_parse_phandle and device_node_to_regmap to get the regmap already assigned by pinctrl driver.
