Currently ImageBuilder can compile and merge partial dts obtained from
a repository specified using PASSTHROUGH_DTS_REPO. With the recent
changes done in the lopper, we can use it to generate partial dts
automatically (to some extent as this is still an early support).
Introduce LOPPER_PATH option to specify a path to a lopper.py script,
the main script in the Lopper repository, that if set, will invoke lopper
to generate partial dts for the passthrough devices specified in
DOMU_PASSTHROUGH_PATHS.
Introduce LOPPER_CMD option to specify custom command line arguments
(if needed) for lopper's extract assist.
Example usage:
LOPPER_PATH="/home/user/lopper/lopper.py"
DOMU_PASSTHROUGH_PATHS[0]="/axi/spi@ff0f0000 /axi/serial@ff010000"

Currently function sanity_check_partial_dts from scripts/common takes
three arguments where the last two (repo, dir) are used always in
conjuction to form a path to a directory storing partial dts. Modify the
function to take only two arguments where the second one is to be a path
to a directory storing partial dts. This will help reusing this function
in the future to perform sanity checks on partial dts that do not
originate from a repository.
Modify compile_merge_partial_dts to take this change into account.

When dealing with device trees, we need to have a solution to add
custom phandles to the nodes we create/modify. Add a global variable
phandle_next to act as a countdown counter starting with the highest
valid phandle value 0xfffffffe. Add a new function get_next_phandle
to get a value of the next available phandle and set it to a variable
whose name is passed as a first argument. The global counter will be
decremented with each call to this function.

If there is any error in compile_merge_partial_dts() and
sanity_check_partial_dts(), it should return 1 to the caller.
The caller will then check the return and call cleanup_and_return_err()
(which terminates the script).
This is to prevent compile_merge_partial_dts() and
sanity_check_partial_dts() terminating the script.
The reason being these functions can get invoked from
disk_image (in the future) which may require some additional
cleanup.
Also, moved cleanup_and_return_err() to uboot-script-gen as the
cleanup is specific to the script.
Ensure that we preseve the directory containing the partial dtbs only
when the dtbs were generated successfully. Else, we delete it.

One should copy the device tree to a temporary file and then make any
change (so as to enable merging of multiple device trees).
In this case, the change is to remove the marker (/dts-v1/;) from all
the device trees except the first one to be merged. DTC expects the
marker to be present only once.
Also, i, j, tmpdts and file should be set to local. This will avoid
name collision.

Extract some of the functions from uboot-script-gen into common.
This will be sourced by disk_image(in subsequent patch) which will
invoke the functions for generating dtb.
common will have access to all the environment variables defined in
the Imagebuilder config file as described in README.md
