Subject[PATCH v9 4/9] PCI: mediatek: Convert to use pci_host_probe()
Date
From: Honghui Zhang <honghui.zhang@mediatek.com>

Part of mtk_pcie_register_host is an open-coded version of
pci_host_probe(). So instead of duplicating this code, use
pci_host_probe() directly and remove mtk_pcie_register_host.
