mmc: omap_hsmmc: Skip platform_get_resource_byname() for dt case
MMC driver probe will abort for DT case because of failed platform_get_resource_byname() lookup. Fix it by skipping resource lookup byname for device tree build. Issue is hidden because hwmod populates the IO resources which helps to succeed platform_get_resource_byname() and probe.
