Raspberry Pi 4's co-processor controls some of the board's HW
initialization process, but it's up to Linux to trigger it when
relevant. Introduce a reset controller capable of interfacing with
RPi4's co-processor that models these firmware initialization routines as
reset lines.

This reverts commit c65822fef4adc0ba40c37a47337376ce75f7a7bc.
The initialization of Raspberry Pi 4's USB chip is now handled through a
reset controller. No need to directly call the firmware routine trough a
pci quirk.

On the Raspberry Pi 4, after a PCI reset, VL805's firmware may either be
loaded directly from an EEPROM or, if not present, by the SoC's
co-processor, VideoCore. This series reworks how we handle this.
The previous solution makes use of PCI quirks and exporting platform
specific functions. Albeit
