[PATCH] i2c: wmt: Use devm_platform_get_and_ioremap_resource()

[ye.xingchen]

From: ye xingchen <ye.xingchen@zte.com.cn>

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.

It's also a cleaner way to handle the error when res is NULL.
