[v4 2/2] ARM: dts: keystone-k2g: Add gpio nodes

[Keerthy]

66AK2G has 2 instances of gpio. The first one has all the 144 GPIOs
functional. 9 banks with 16 gpios making a total of 144. The second
instance has only the GPIO0:GPIO67 functional and rest are marked
reserved.

Changes in v4:

  * Couple of rephrasing in the commit log.
  * Changed compatible to ti,k2g-gpio.

Changes in v2:

  * Split the documentation part into a separate patch.
