crypto: fix selecting of digests ...

SHA1 is meant as a boolean option which is true when sha1 support is available.
This works because the providers (DIGEST_SHA1_GENERIC and DIGEST_SHA1_ARM) have
a 'select SHA1'. However, consumers like the sha1sum command do a 'select SHA1'
to enable SHA1 support. This of course does not work; selecting SHA1 will not
select any of the SHA1 providers.

This is broken for all digest consumers. We have to explicitly select a digest
provider, that is DIGEST_*_GENERIC to enable the corresponding digest.

This means now we will always have the generic digest in the binary, even
when an optimized one is enabled. There is no sane way in Kconfig to
"select provider for feature xy", so let's live with the overhead in the binary.

PBL: console: Make independent of DEBUG_LL ...

With more stuff being done in PBL regular console support gets more and more
useful. This makes the PBL console independent of DEBUG_LL which is only
meant for early debugging but not regular output.
To use the regular PBL console a board must call pbl_set_putc() which stores
a pointer to the putc function to be used.

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:

Add PBL console support ...

This adds simple console support to the PBL which makes it
possible to print more complex messages in the PBL than just
strings or hex numbers. For now puts_ll is used to print the
messages, so it depends on CONFIG_DEBUG_LL which makes it
more a debugging option. However, this could be extended later
to get regular output from the PBL if desired.

This moves the variable assignments previously done in /env/config-board

by the user without editing a file.

Most of the changes are simple conversions which for many boards makes
/env/config-board unnecessary. Some boards had some logic to assign
global.boot.default based on the current bootsource. This has been
moved to /env/init/bootsource. An additional check is added to not
overwrite a nv.boot.default should it exist.
