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 8/9] net: phy: phy_device: Call into the PHY driver to set LED
+ blinking
+
+Linux LEDs can be requested to perform hardware accelerated
+blinking. Pass this to the PHY driver, if it implements the op.
