Subject: [PATCH v4] dt-bindings: leds: Expand LED_COLOR_ID definitions

In commit 853a78a7d6c7 (dt-bindings: leds: Add LED_COLOR_ID definitions,
Sun Jun 9 20:19:04 2019 +0200) the most basic color definitions where
added. However, there's a little more very common LED colors.

While the documentation states 'add what is missing', engineers tend to
be lazy and will just use what currently exists. So this patch will take
(a) list from online retailers [0], [1], [2] and use the common LED colors from
there, this being reasonable as this is what is currently available to purchase.

Note, that LIME seems to be the modern take to 'Yellow-green' or
'Yellowish-green' from some older datasheets.
