net: fec: do not double-parse 'phy-reset-active-high' property
Conversion to gpiod API done in commit 468ba54bd616 ("fec: convert to gpio descriptor") clashed with gpiolib applying the same quirk to the reset GPIO polarity (introduced in commit b02c85c9458c). This results in the reset line being left active/device being left in reset state when reset line is "active low". Remove handling of 'phy-reset-active-high' property from the driver and rely on gpiolib to apply needed adjustments to avoid ending up with the double inversion/flipped logic.
