net: emaclite: Use devm_platform_get_and_ioremap_resource() in xemaclite_of_probe()

A wrapper function is available since the commit 890cc39a
("drivers: provide devm_platform_get_and_ioremap_resource()").
Thus reuse existing functionality instead of keeping duplicate source code.

This issue was detected by using the Coccinelle software.
