Subject: [PATCH] phy/mediatek: Make PHY_MTK_XSPHY depend on HAS_IOMEM and OF_ADDRESS to fix build errors

devm_ioremap_resource() will be not built in lib/devres.c if
CONFIG_HAS_IOMEM is not set, of_address_to_resource() will be
not built in drivers/of/address.c if CONFIG_OF_ADDRESS is not
set, and then there exists two build errors about undefined
reference to "devm_ioremap_resource" and "of_address_to_resource"
in phy-mtk-xsphy.c under COMPILE_TEST and CONFIG_PHY_MTK_XSPHY,
make PHY_MTK_XSPHY depend on HAS_IOMEM and OF_ADDRESS to fix it.
