Add gpio-ranges properties to the gpio controller nodes.

These gpio-ranges were created based on "Table 9-10. CONTROL_MODULE
REGISTERS" in the  "AM335x Technical Reference Manual" [0] and "Table
4-2. Pin Attributes" in the "AM335x Sitara Processor datasheet" [1].
A csv file with this data is available for reference [2].
It will be good if you can explain not only "what" is changed, but
also "why" it's needed in commit message.
Also, please check (again) that this is the same for all the am3
variants. For omap3, we had different pad assignments even between
SoC revisions. Different pad routings should be easy to deal with
in the dts if needed though.

Regards,

Tony
