Merge branch 'net-phy-generic-polarity-led-support-for-qca808x' 

Christian Marangi says:

====================
net: phy: generic polarity + LED support for qca808x

This small series add LEDs support for qca808x.

QCA808x apply on PHY reset a strange polarity settings and require
some tweak to apply a more common configuration found on devices.
On adding support for it, it was pointed out that a similar
feature is also being implemented for a marvell PHY where
LED polarity is set per LED (and not global) and also have
a special mode where the LED is tristated.

The first 3 patch are to generalize this as we expect more PHY
in the future to have a similar configuration.

The implementation is extensible to support additional special
mode in the future with minimal changes and don't create regression
on already implemented PHY drivers.
