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] leds: Move led_init_default_state_get() to the global header
+
+There are users inside and outside LED framework that have implemented
+a local copy of led_init_default_state_get(). In order to deduplicate
+that, as the first step move the declaration from LED header to the
+global one.

+Subject: [PATCH 1/9] net: dsa: qca8k: move qca8k_port_to_phy() to header
+
+Move qca8k_port_to_phy() to qca8k header as it's useful for future
+reference in Switch LEDs module since the same logic is applied to get
+the right index of the switch port.
+Make it inline as it's simple function that just decrease the port.
