misc: add ACPI test driver ...

We have a bus driver for ACPI, but no drivers yet. Add a simple (rather
useless) driver that exercises the API, which future drivers can be
based on. As soon as we have proper ACPI drivers, this driver could be
removed again.

ubootvarfs: depend on OFTREE ...

This driver can only be probed from DT and needs some OFTREE only
functions to work correctly. Depend on the config option to make
sure they are available.

misc: Add a driver to expose U-Boot environment variable data ...

Add a driver to expose U-Boot environment variable data as a single
mmap-able device, hiding various low-level details such as:

    * Preamble format differences
    * Read/write logic in presence of redundant partition

Not very useful on its own, it is a crucial low-level plumbing needed
by filesystem driver introduced in the following commit.

commands: Move /dev/mem driver to drivers/misc ...

With all other code gone from commands/mem.c, move it into
driver/misc, where it fits better. While at it, expose it directly via
a Kconfig options instead of relying on CONFIG_COMPILE_MEMORY

state: Fix Kconfig dependencies ...

State support does not need OF_BAREBOX_DRIVERS and never did, so drop
the dependency there. It's the state driver which needs of_find_path(),
since this symbol now is always enabled when OF is enabled, we don't
have to add the dependency to the state driver, but instead can depend
on OFDEVICE. We could depend on OF instead, but compiling the state
driver without OFDEVICE makes no sense.

state: add framework for persistent state handling ...

This patch adds a framework to describe, access, store and restore a set of
variables. A state variable set can be fully described in a devicetree node.
This node could be part of the regular devicetree blob or it could be an extra
devicetree solely for the state. The state variable set contains variables of
different types and a place to store the variable set.

For more information see:
    Documentation/devicetree/bindings/barebox/barebox,state.rst

misc Kconfig: always ask for misc devices ...

The "Misc devices" menu does not enable anything by itself, so make it a
regular menu rather than a menuconfig.
