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.

Move the code into a helper, ready for it to be called at
