arm64: dts: ti: k3-j722s: Add gpio-ranges properties

The AM67A/J722S/TDA4AEN platform is a derivative of AM62P platform
and we have no single 1:1 relation regarding index of GPIO and pin
controller. The GPIOs and pin controller registers have mapping and
holes in the map. These have been extracted from the J722S data
sheet. The MCU mapping is carried forward as is with J722S, however the
main GPIO block has differences that needs to be accounted for.

Mux mode input is selected as it is bi-directional. In case a specific
pull type or a specific pin level drive setting is desired, the board
device tree files will have to explicitly mux those pins for the GPIO
with the desired setting.
