drivers/net/r8168: Modify to support RTL8125 LEDs
The Realtek RTL8125 has four registers for four leds
and a feature config register.
We use led0 and led2 in brask, so modify ethernet driver.
Those registers' IO address are based on RTL8125 datasheet.
BUG=b:193750191
TEST=Modify overridetree.cb to verify LEDs' settings.
