gpio: omap_gpio: Convert to auto-alloc feature when DT is supported

Browse source 
The omap_gpio driver has a TODO that says when every board is converted
to DM and DT, the omap_gpio_bind can stop using calloc and switch
to auto-alloc.

This patch converts this driver to auto-calloc when DT is enabled.
