[PATCH v8 0/4] 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.  Each driver is selected on the
appropriate QEMU board.  A sandbox driver is also added, and a DM unit
test against that driver.  The qfw command is tested in QEMU, and
documentation added.

Version 7 ensures the qfw test assertions work both against real QEMU
instances and the sandbox and removes CMD_QFW from the sandbox_spl
config.  Version 8 removes some extraneous whitespace.

Changes in v8:
* Removed extraneous newlines at EOF.

Changes in v7:
* Make the qfw tests agnostic to running against a real QEMU instance or
  in the sandbox.
* Remove CONFIG_CMD_QFW=y from sandbox_spl_defconfig, per trini's
  request.

Changes in v6:
* Sandbox driver and tests are split into own commit.

Changes in v5:
* Split conversion of existing x86-only QFW to DM into its own patch.
* Split MMIO driver into its own commit.
* Split adding MMIO driver to QEMU arm/64 into own commit.
