[net-next,2/2] net: phy: qcom: qca808x: default to LED active High if not set

qca808x PHY provide support for the led_polarity_set OP to configure
and apply the active-low property but on PHY reset, the Active High bit
is not set resulting in the LED driven as active-low.

To fix this, check if active-low is not set in DT and enable Active High
polarity by default to restore correct funcionality of the LED.
