airoha: an7581: add PHY LEDs for the Gemtek W1700K

Browse Source 
Both 10G ports have a yellow and a green LED driven by the RTL8261CE
rather than by GPIO. Index 2 is yellow, index 3 green. The
index-to-colour mapping was determined empirically by inverting the
polarity bits in VEND2 0xd044 one at a time.

Configure the triggers to match the 1G ports on this board, where green
means gigabit: yellow for 10/100, green from 1000 up, and both together
for 10000. Without this the LEDs come up with no trigger and stay dark,
losing the firmware defaults they had before.

The indices were only verified on an RTL8261CE. Board revisions carrying an
RTL8261N are unaffected for now since that driver has no LED callbacks, but
the mapping should be rechecked there before relying on it.
