It seems I misread your original mail. Turns out reset-raspberrypi and xhci_pci
configs are already linked as they should:

	config RESET_RASPBERRYPI
		tristate "Raspberry Pi 4 Firmware Reset Driver"
		depends on RASPBERRYPI_FIRMWARE || (RASPBERRYPI_FIRMWARE=n && COMPILE_TEST)
	>>	default USB_XHCI_PCI
		help
		  [...]

Your initramfs fix looks OK to me.

Regards,
Nicolas
