generic: backport initial LEDs hw control support
Backport initial LEDs hw control support. Currently this is limited to
only rx/tx and link events for the netdev trigger but the API got
accepted and the additional modes are working on and will be backported
later.

Refresh every patch and add the additional config flag for QCA8K new
LEDs support.

Subject: [PATCH] net: dsa: add Qualcomm IPQ4019 built-in switch support
Qualcomm IPQ40xx SoC-s have a variant of QCA8337N switch built-in.
It shares most of the stuff with its external counterpart, however it is
modified for the SoC.
Namely, it doesn't have second CPU port (Port 6), so it has 6 ports
instead of 7.
It also has no built-in PHY-s but rather requires external PSGMII based
companion PHY-s (QCA8072 and QCA8075) for which it first needs to carry
out calibration before using them.
PSGMII has a SoC built-in PHY that is used to connect to the PHY-s which
unfortunately requires some magic values as the datasheet doesnt document
the bits that are being set or the register at all.
Since its built-in it is MMIO like other peripherals and doesn't have its
own MDIO bus but depends on the SoC provided one.
CPU connection is at Port 0 and it uses some kind of a internal connection
and no traditional RGMII/SGMII.
It also doesn't use in-band tagging like other qca8k switches so a shinfo
based tagger is used.
