[PATCH 1/2] PCI: Implement pci_reset_function_locked

The implementation of PCI workarounds may require that the device is reset from its probe function. This implies that the PCI device lock is already held, and makes calling pci_reset_function impossible (since it will itself try to take that lock). This patch introduces pci_reset_function_locked,

[PATCH 2/2] usb: host: pci_quirks: Force hard reset of Renesas uPD72020x USB controller
