Donggeun Yoo 6ca81bbc31 net: phy: dp83td510: handle the active-high LED polarity mode 
dp83td510_led_polarity_set() only recognizes PHY_LED_ACTIVE_LOW, so
PHY_LED_ACTIVE_HIGH falls through to the default case and returns -EINVAL.
of_phy_led() propagates the error, of_phy_leds() drops the LEDs registered
so far and passes it on, and phy_probe() returns it. A device tree marking
a DP83TD510 LED as 'active-high', which leds/common.yaml allows and
ethernet-phy.yaml references for led@N nodes, thus leaves the mdio device
unbound, so phy_attach_direct() falls back to the genphy driver, which
cannot drive this 10BASE-T1L single-mode PHY, so the interface has no
usable link.

The callback initializes polarity to DP83TD510E_LED_POLARITY(index), which
is the active-high setting, so the request is already satisfied and only
the case label is missing.
