Subject: [PATCH] serial: fsl_lpuart: Use
 devm_platform_get_and_ioremap_resource()

References: bsc#1214683 (PREEMPT_RT prerequisite backports)
Patch-mainline: v6.6-rc1
Git-commit: 8f3c8d8152532e0065070385258404e2aa7f1f45

Convert platform_get_resource(), devm_ioremap_resource() to a single
call to devm_platform_get_and_ioremap_resource(), as this is exactly
what this function does.
