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.
Fixes: 468ba54bd616 ("fec: convert to gpio descriptor")
