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 9/9] net: phy: marvell: Implement led_blink_set()
+
+The Marvell PHY can blink the LEDs, simple on/off. All LEDs blink at
+the same rate, and the reset default is 84ms per blink, which is
+around 12Hz.
