Subject: drm/panfrost: Make use of the helper function
 devm_platform_ioremap_resource()
Git-commit: 3605eacc8ae055d699f7fa3adb9123c4c36ecd82
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
