The System Control Unit (SCU) controller of Aspeed
SoCs provides the reset control for each peripheral.

This patch refactors the reset method to leverage
the SCU reset control. Thus the driver dependency
on watchdog including dedicated WDT API and reset
flag encoding can be eliminated.

The Kconfig description is also updated accordingly.

Instead having a hard coded value for "cramfsaddr" after compile time,
we change it to take the variable "cramfsaddr" for the ubicopy variable.
This makes sure that ubicopy uses the right address, even when

Due to increasing kernel image sizes we get problems when decompressing
the kernel image. To fix this we need to change the addresses where we
load and where we extract the kernel. Also we need to adapt the address
where to load the CRAMFS image and where to load the DTB file.
While at it also harmonize all boards for PPC and ARM to have the
same values. Also we add a new variable "env_version", so that the
userspace is able to detect if this is a u-boot binary with updated
values or not.

This code is intended do prevent one from setting a shell variable abc
by doing

  abc=123

if an environment variable named abc already exists. However, the
check is broken, since the env_get is done before the split on =, so
we look up whether an environment variable "abc=123" exists, which is
obviously never the case.

One could move the code to below the split on =, but instead, just
remove it, saving a little .text: The check has never worked as
intended (it goes all the way back to the initial git commit), and it
would anyway not guard against one first setting the shell variable,
then doing 'env set abc xyz'.
