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 3/5] leds: trigger: netdev: Rename add namespace to netdev
trigger enum modes
Rename NETDEV trigger enum modes to a more symbolic name and add a
namespace to them.
Also add __TRIGGER_NETDEV_MAX to identify the max modes of the netdev
trigger.
This is a cleanup to drop the define and no behaviour change are
intended.
