drm: xlnx: Use devm_platform_ioremap_resource_byname() helper function

Commit Message

Zhang Zekun Aug. 11, 2023, 2:11 a.m. UTC

platform_get_resource_byname() and devm_ioremap_resource() can be
replaced by devm_platform_ioremap_resource_byname(), which can
simplify the code logic a bit, No functional change here.
