====================
net: phy: qca808x: fix the active-high LED polarity mode

A QCA8081 with an 'active-high' LED node does not work today, in two
separate ways, so this is now two patches: qca808x_led_polarity_set()
rejects the mode outright, and once it stops doing that
qca808x_config_init() still will not put the bit back after the reset
phy_init_hw() runs.

Tested in QEMU against a synthetic MDIO bus that answers as a QCA8081 and
emulates MMD7 0x901a, with the reset clearing BIT(6) as f203c8c77c
describes. One kernel, one harness, three arms, x86_64, 7.3.0-rc2+:

  DT node            base      1/2 only   1/2 + 2/2
  active-high        -EINVAL   inverted   correct
  active-low         correct   correct    correct
  no polarity node   correct   correct    correct
  high-impedance     -EINVAL   -EINVAL    -EINVAL

Still no QCA808x hardware here; the harness emulates the one register,
so a confirmation on a real board would be welcome.
