[PATCH net v3 1/2] net: phy: qca808x: accept the active-high LED polarity mode

[Donggeun Yoo <donggeunyoo.kernel@gmail.com>]

commit a274465cc3be ("net: phy: support 'active-high' property for PHY LEDs")
added PHY_LED_ACTIVE_HIGH, but qca808x_led_polarity_set() still rejects
everything except PHY_LED_ACTIVE_LOW. An LED node carrying 'active-high'
therefore falls into the default case and returns -EINVAL, which
phy_probe() propagates: the mdio device is left unbound and
phy_attach_direct() falls back to the genphy driver, so the PHY loses
every qca808x-specific feature, not just the LED.

Accept the mode. The register write below already handles both
polarities.

Tested in QEMU against a synthetic MDIO bus answering as a QCA8081; see
the cover letter for the three-arm table.
