arm64: dts: ti: k3-am62-main: Add gpio-ranges properties

On the AM62 platform we have no single 1:1 relation regarding index of
gpio and pin controller. Actually there are some linear ranges with
small holes inbetween. These ranges can be represented with the
gpio-ranges device tree property. They have been extracted manually
from the AM62x datasheet (Table 6-1. Pin Attributes).
