Subject: [PATCH v2 0/2] Raspberry Pi 4 VL805 firmware load

Newer revisions of the RPi4 need their xHCI chip, VL805, firmware to be
loaded explicitly. Earlier versions didn't need that as they where using
an EEPROM for that purpose. This series takes care of setting up the
relevant infrastructure and run the firmware loading routine at the
right moment.

Note that this builds on top of Sylwester Nawrocki's "USB host support
for Raspberry Pi 4 board" series.

Changes since v1:
 - Rename function
 - Use callback in xhci-pci.c

  arm: rpi: Add function to trigger VL805's firmware load
