Subject: [PATCH] i2s: Simplify resource retrieval and mapping by using
 devm_platform_get_and_ioremap_resource

From: Peng Jiang <jiang.peng9@....com.cn>

Convert platform_get_resource(), devm_ioremap_resource() to a single call
to devm_platform_get_and_ioremap_resource().

By making this change, we improve code readability and reduce redundancy
without affecting the functionality of the driver.
