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

References: bsc#1214683 (PREEMPT_RT prerequisite backports)
Patch-mainline: v6.6-rc1
Git-commit: 8c6d7e5fd50b451b4de1c42e8b9faad5257fa12e

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.
