[PATCH 0/2] Use devm_platform_ioremap_resource_byname in phy

[shao.mingyin]

From: Xie Ludan <xie.ludan@zte.com.cn>

Introduce devm_platform_ioremap_resource_byname() to simplify resource
retrieval and mapping.This new function consolidates
platform_get_resource_byname() and devm_ioremap_resource() into
a single call, improving code readability and reducing API call overhead.
