[PATCH] iommu/ipmmu-vmsa: use devm_platform_get_and_ioremap_resource()

[<ye.xingchen@zte.com.cn>]

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.
