Christian Marangi cf08db988b 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 10/13] leds: trigger: netdev: init mode if hw control already
active
On netdev trigger activation, hw control may be already active by
default. If this is the case and a device is actually provided by
hw_control_get_device(), init the already active mode and set the
bool to hw_control bool to true to reflect the already set mode in the
trigger_data.
