[PATCH-V2 3/6] ARM: dts: AM33XX: Fix gpio numbering to match hardware/TRM

With DT support, where naming convention is based on base-addr
and not id, so we should follow TRM/Spec numbering label.
This patch changes GPIO numbering as per TRM, as gpio0-3.
Matt Porter had submitted base patch sometime back but it
didn't make it to the mainline -
https://patchwork.kernel.org/patch/1433001/
Later DT nodes for gpio based keypad and led driver got
merged, so this fix needs to propagate to board dts files
as well.
