gpio: omap_gpio: Convert to auto-alloc feature when DT is supported
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. Signed-off-by: Adam Ford <aford173@gmail.com>
