It is necessary to introduce a new system wide function- power_init_board()
It turns out, that power initialization must be done as early as possible.
In the case of PMIC framework redesign, which aims to support multiple
instances of PMIC devices the initialization shall be performed just
after malloc configuration.
The power_init_board function is a weak function with default implementation.

The PMIC framework has been extended to support multiple instances of
the variety of devices responsible for power management.
This change allows supporting of e.g. fuel gauge, charger, MUIC (Micro USB
Interface Circuit).
Power related includes have been moved to ./include/power directory.
This is a first of a series of patches - in the future "pmic" will be
replaced with "power".
Two important issues:
1. The PMIC needs to be initialized just after malloc is configured
2. It uses list to hold information about available PMIC devices

Commit 97b24d3d51 "common: Add symbol
handling for generic lists into Makefile" introduced build errors in many
nand_spl targets, complaining of a missing u-boot.lst. When not doing an
out-of-tree build, $(obj) expands to nothing, so GCC ended up being given
-I with no argument (or rather, -ansi was the argument). The failure
didn't show up during a -j1 build because it was picking up the non-SPL
version of u-boot.lst.

If kernel-offset is specified in the fdt, set an environment variable
so that scripts can access the attached kernel.
This can be used by a packaging program to tell U-Boot about a kernel
that has been downloaded alongside U-Boot. The value in the fdt is
the offset of the kernel from the start of the U-Boot image, so we can
find it just by adding CONFIG_SYS_TEXT_BASE.
It is then fairly easy to put something like this in the environment
variables in the board header file:
"if test ${kernaddr} != \"\"; then "\
"echo \"Using bundled kernel\"; "\
"bootm ${kernaddr};" \
"fi; "\
/* rest of boot sequence follows here */

When booting a fit image with multiple configurations, the user either has to
specify which configuration to use explicitly, or there has to be a default
defined which is chosen automatically. This change adds an option to change
that behavior so that a configuration can be selected explicitly, or the
configuration which has the device tree that claims to be compatible with the
earliest item in U-Boot's device tree.
In other words, if U-Boot claimed to be compatible with A, B, and then C, and
the configurations claimed to be compatible with A, D and B, D and D, E, the
first configuration, A, D, would be chosen. Both the first and second
configurations match, but the first one matches a more specific entry in
U-Boot's device tree. The order in the kernel's device tree is ignored.

When secure booting is chosen:
* The u-boot shell is never invoked during boot--we just do a simple
table lookup to find the command. This means we could even remove
the shell parsing from u-boot and still be able to boot.
* The boot command can't be interruped.
* Failure doesn't cause us to fall back to the shell.
