make PBL_CONSOLE depend on PBL_IMAGE ...

PBL_CONSOLE option is used only for building PBL. See this output:

    barebox$ git grep PBL_CONSOLE
    arch/arm/configs/tx28stk5_defconfig:CONFIG_PBL_CONSOLE=y
    common/Kconfig:config PBL_CONSOLE
    common/Makefile:pbl-$(CONFIG_PBL_CONSOLE)       += memory_display.o
    include/printk.h:       (defined(__PBL__) && defined(CONFIG_PBL_CONSOLE))
    include/stdio.h:        (defined(__PBL__) && defined(CONFIG_PBL_CONSOLE))
    lib/Makefile:pbl-$(CONFIG_PBL_CONSOLE) += vsprintf.o
    pbl/Makefile:pbl-$(CONFIG_PBL_CONSOLE) += console.o

PBL_CONSOLE looks confusing in PBL-less configuration
so it's better to enable it only if PBL is enabled.

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

ARM/mem: handle data aborts gracefully for md ...

Sometimes memory ranges contain inaccessible registers which trigger a
data abort when accessed. To handle this gracefully, we extend the data
abort exception handler to ignore the exception when configured to do
so.

This allows detecting inaccessible memory from the md command. It will
show XX for unreadable bytes instead.

The previous behaviour:

The current implementation breaks everything except ARM and takes several
shortcuts which need to be implemented more cleanly. Suggestions are very
