We move qfw into its own uclass and split the PIO functions into a specific driver for that uclass. The PIO driver is selected in the qemu-x86 board config (this covers x86 and x86_64).
include/qfw.h is cleaned up and documentation added.

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.
- Fix qfw_get_dev() so it actually returns -ENODEV when device is
missing.
- Add CONFIG_QFW_PIO.
- Choose CONFIG_QFW_PIO in board/emulation/qemu-x86/Kconfig.
- QFW sandbox driver no longer inserts itself from device tree; wasn't
relevant to implementation and the ``compatible'' string was too made-up. Use U_BOOT_DRVINFO like the other QFW driver in this patch.
- Relevant documentation and sandbox/qemu tests are now here.
