usb: xhci: Raspberry Pi FW loader for VIA VL805



The VL805 FW may either be loaded from an SPI EEPROM or alternatively
loaded directly by the VideoCore firmware. A PCI reset will reset
the VL805 XHCI controller on the Raspberry Pi4 requiring the firmware
to be reloaded if an SPI EEPROM is not present.

Use a VideoCore mailbox to trigger the loading of the VL805
firmware (if necessary) after a PCI reset.
