[PATCH] ARM: BCM53573: Specify ports for USB LED for Tenda AC9

[Rafał Miłecki]

From: Rafał Miłecki <rafal at milecki.pl>

This uses trigger-sources documented in commit 80dc6e1cd85fc ("dt-bindings:
leds: document new trigger-sources property") to specify USB ports. Such an
information can be used by operating system to setup LEDs behavior.
