Prior to Kbuild, $(TOPDIR) or $(SRCTREE) was used for
pointing to the top of source directory.
(No difference between the two.)
In Kbuild style, $(srctree) is used for instead.
This commit renames SRCTREE to srctree and deletes the
defition of SRCTREE.
Note that SRCTREE in scripts/kernel-doc, scripts/docproc.c,
doc/DocBook/Makefile should be keep.

This commit changes the working directory
where the build process occurs.
Before this commit, build process occurred under the source
tree for both in-tree and out-of-tree build.
That's why we needed to add $(obj) prefix to all generated
files in makefiles like follows:
$(obj)u-boot.bin: $(obj)u-boot
Here, $(obj) is empty for in-tree build, whereas it points
to the output directory for out-of-tree build.
And our old build system changes the current working directory
with "make -C <sub-dir>" syntax when descending into the
sub-directories.
On the other hand, Kbuild uses a different idea
to handle out-of-tree build and directory descending.
The build process of Kbuild always occurs under the output tree.
When "O=dir/to/store/output/files" is given, the build system
changes the current working directory to that directory and
restarts the make.
Kbuild uses "make -f $(srctree)/scripts/Makefile.build obj=<sub-dir>"
syntax for descending into sub-directories.
(We can write it like "make $(obj)=<sub-dir>" with a shorthand.)
This means the current working directory is always the top
of the output directory.

For most boards which define CONFIG_SPL_PAD_TO,
it is defined in config header files.
Currently, there exists only one exception, cam_enc_4xx board.
This patch moves CONFIG_SPL_PAD_TO definition
from board/ait/cam_enc_4xx/config.mk
to include/configs/cam_enc_4xx.h.
With this modification, we can delete a glue code
in the top level config.mk:
ifneq ($(CONFIG_SPL_PAD_TO),)
CPPFLAGS += -DCONFIG_SPL_PAD_TO=$(CONFIG_SPL_PAD_TO)
endif

This was already used by some SPL targets, and allows the pad amount to
be specified by board config headers rather than only in makefile
fragments.
Also supply a pad-to of zero if the variable is undefined. It works
without this, but this avoids relying on undocumented behavior.

- change CONFIG_ENV_RANGE to contain 2 nand erase blocks,
one for bad block reserve.
- remove from the envvariable "img_writeramdisk" the
ubifsmount command, as it is not needed.
- erase the hole mtd partition containing u-boot
- save environment variable "dvn_app_vers" and "dvn_boot_vers"
only after installing the new image.
