net: phy: mediatek: do not require syscon compatible for pio property 



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.
