Subject: drm: rcar-du: Make use of the helper function
devm_platform_ioremap_resource()
Git-commit: c2419077714d0ebd01c2eea0fb4d510c630457c1
Patch-mainline: v5.16-rc1
References: jsc#PED-1166 jsc#PED-1168 jsc#PED-1170 jsc#PED-1218 jsc#PED-1220 jsc#PED-1222 jsc#PED-1223 jsc#PED-1225
Use the devm_platform_ioremap_resource() helper instead of
calling platform_get_resource() and devm_ioremap_resource()
separately
