[PATCH v4 0/5] Move qfw to DM, add Arm support

[Asherah Connor]

This series moves the QFW driver into a uclass, UCLASS_QFW, and splits
the driver into qfw_pio and qfw_mmio.  A sandbox driver is also added,
and a DM unit test against that driver.

On x86 a U_BOOT_DRVINFO is used to configure the qfw_pio (with compiled-
in constants used for PIO ports), otherwise we configure qfw_mmio from
device tree if present.

Version 4 of this series adds a test for the qfw command, exercising it
on QEMU in test/py/tests/test_qfw.py.  The introductory "move QFW to DM"
commit has been rolled into the uclass split one.  Documentation is
added.
