Subject: [PATCH v2 3/3] PCI: mediatek-gen3: Make use of the helper function devm_platform_get_and_ioremap_resource_byname()

Use the devm_platform_get_and_ioremap_resource_byname() helper
instead of calling platform_get_resource_byname() and
devm_ioremap_resource() separately.

Signed-off-by: Cai Huoqing <caihuoqing@...du.com>

v1->v2: Use devm_platform_get_and_ioremap_resource_byname()
	instead of devm_platform_ioremap_resource_byname().
