Make COMMON_CLK_OF_PROVIDER depend on OFTREE, this way checking for:
defined(CONFIG_OFTREE) && defined(CONFIG_COMMON_CLK_OF_PROVIDER)
can be simplified to just:
defined(CONFIG_COMMON_CLK_OF_PROVIDER)

In barebox_non_pbl_start() we do not run at the address we are linked
at, so we must read linker variables using ld_var(). Since ld_var()
current is not available on arm64 we create two zero sized arrays,
one at the begin of the image and one at the end. The difference
between both is the image size we are looking for.

Sometimes a single software control knob controls multiple gates
in hardware. This patch adds support for shared gates which help
coping this situation. The first gate is registered with the hardware
gate as usual, the others are registered as shared gates which does
not have hardware control itself, but only switches the real hardware
gate.

Some clocks may only be modified when their parent clocks are enabled.
The kernel has the CLK_OPS_PARENT_ENABLE flag for this purpose.

'[m' is supposed to have the same effect as '[0m'. However, some EFI

So far the eMMC boot partitions cannot be partitioned from the
device tree. Since they are often 4MiB in size they are big enough
to hold a barebox image and the environment. Add partition parsing
to the boot partitions to allow this usecase.

This adds `filetype_squashfs` to the list of known filetypes and adds a
detection for squashfs files to file_detect_type(). This currently
matches on the `hsqs` start sequence of an image file.
Additionally, the newly introduced filetype is registered as the type of
the squashfs_driver which allows, for example, to mount squashfs without
the need to specify a type parameter.
This changes enable booting a squashfs with the simple `boot` command
pointing to the location (device) that holds the squashfs.
Note that booting with blspec is limited as the current squashfs driver
is not capable of handling symbolic links.

There are several use cases where a redundant Linux system is needed. The
barebox bootchooser framework provides the building blocks to model different
use cases without the need to start from the scratch over and over again.
The bootchooser works on abstract boot targets, each with a set of properties
and implements an algorithm which selects the highest priority target to boot.
See the documentation contained in this patch for more information.
